Program to accept String starting with Capital letter Last Updated : 24 Oct, 2022 Comments Improve Suggest changes Like Article Like Report Given a string str consisting of alphabets, the task is to check whether the given string is starting with a Capital Letter or Not.Examples: Input: str = "GeeksforGeeks"Output: Accepted Input: str = "geeksforgeeks"Output: Not Accepted Approach: Find the ASCII value of the first character of the string Check if this value lies in the range of [65, 90] or not If yes, print AcceptedElse print Not Accepted Below is the implementation of the above approach: C++ // C++ program to accept String // starting with Capital letter #include <iostream> using namespace std; // Function to check if first // character is Capital int checkIfStartsWithCapital(string str) { if (str[0] >= 'A' && str[0] <= 'Z') return 1; else return 0; } // Function to check void check(string str) { if (checkIfStartsWithCapital(str)) cout << "Accepted\n"; else cout << "Not Accepted\n"; } // Driver function int main() { string str = "GeeksforGeeks"; check(str); str = "geeksforgeeks"; check(str); return 0; } Java // Java program to accept String // starting with Capital letter class GFG { // Function to check if first // character is Capital static int checkIfStartsWithCapital(String str) { if (str.charAt(0) >= 'A' && str.charAt(0) <= 'Z') return 1; else return 0; } // Function to check static void check(String str) { if (checkIfStartsWithCapital(str) == 1) System.out.println("Accepted"); else System.out.println("Not Accepted"); } // Driver function public static void main(String[] args) { String str = "GeeksforGeeks"; check(str); str = "geeksforgeeks"; check(str); } } // This code is contributed by AnkitRai01 Python3 # Python3 program to accept String # starting with Capital letter # Function to check if first # character is Capital def checkIfStartsWithCapital(string): if (string[0] >= 'A' and string[0] <= 'Z'): return 1 else: return 0 # Function to check def check(string): if (checkIfStartsWithCapital(string)): print("Accepted") else: print("Not Accepted") # Driver function if __name__ == "__main__": string = "GeeksforGeeks" check(string) string = "geeksforgeeks" check(string) # This code is contributed by AnkitRai01 C# // C# program to accept String // starting with Capital letter using System; class GFG { // Function to check if first // character is Capital static int checkIfStartsWithCapital(string str) { if (str[0] >= 'A' && str[0] <= 'Z') return 1; else return 0; } // Function to check static void check(string str) { if (checkIfStartsWithCapital(str) == 1) Console.WriteLine("Accepted"); else Console.WriteLine("Not Accepted"); } // Driver function public static void Main() { string str = "GeeksforGeeks"; check(str); str = "geeksforgeeks"; check(str); } } // This code is contributed by AnkitRai01 JavaScript <script> // JavaScript program to accept String // starting with Capital letter // Function to check if first // character is Capital function checkIfStartsWithCapital(str) { if (str[0] >= 'A' && str[0] <= 'Z') return 1; else return 0; } // Function to check function check(str) { if (checkIfStartsWithCapital(str)) document.write( "Accepted<br>"); else document.write( "Not Accepted<br>"); } // Driver function var str = "GeeksforGeeks"; check(str); str= "geeksforgeeks"; check(str); </script> Output: Accepted Not Accepted Time complexity: O(1)Auxiliary space: O(1) Comment More infoAdvertise with us Next Article Program to accept String starting with Capital letter C code_r Follow Improve Article Tags : Strings Computer Science Fundamentals DSA Practice Tags : Strings Similar Reads DSA Tutorial - Learn Data Structures and Algorithms DSA (Data Structures and Algorithms) is the study of organizing data efficiently using data structures like arrays, stacks, and trees, paired with step-by-step procedures (or algorithms) to solve problems effectively. Data structures manage how data is stored and accessed, while algorithms focus on 7 min read Quick Sort QuickSort is a sorting algorithm based on the Divide and Conquer that picks an element as a pivot and partitions the given array around the picked pivot by placing the pivot in its correct position in the sorted array. It works on the principle of divide and conquer, breaking down the problem into s 12 min read Merge Sort - Data Structure and Algorithms Tutorials Merge sort is a popular sorting algorithm known for its efficiency and stability. It follows the divide-and-conquer approach. It works by recursively dividing the input array into two halves, recursively sorting the two halves and finally merging them back together to obtain the sorted array.

Understanding data structures is very important for developing efficient and effective algorithms.

This algorithm is not suitable for large data sets as its average and worst-case time complexity are quite high.We sort the array using multiple passes.

Perform a Breadth First Search (BFS) traversal starting from vertex 0, visiting vertices from left to right according to the adjacency list, and return a list conta 15+ min read Binary Search Algorithm - Iterative and Recursive Implementation Binary Search Algorithm is a searching algorithm used in a sorted array by repeatedly dividing the search interval in half. The idea of binary search is to use the information that the array is sorted and reduce the time complexity to O(log N).

It is like sorting playing cards in your hands. You split the cards into two groups: the sorted cards and the unsorted cards.

The graph contains V vertices, numbered from 0 to V - 1.Note: The given graph does not contain any negative edge. Example 12 min read Selection Sort Selection Sort is a comparison-based sorting algorithm. It sorts an array by repeatedly selecting the smallest (or largest) element from the unsorted portion and swapping it with the first unsorted element. This process continues until the entire array is sorted.First we find the smallest element an 8 min read Like
