C Program to Remove All Occurrences of an Element in an Array Last Updated : 02 Aug, 2022 Comments Improve Suggest changes Like Article Like Report To remove all the occurrences of an element in an array, we will use the following 2 approaches: Using MethodsWithout using methods or With Conditional Statement We will keep the same input in all the mentioned approaches and get an output accordingly. Input: array = {1, 2, 1, 3, 1} value = 1 Output: array = {2, 3} Explanation: The given value 1 is to be removed from the array of elements. So, the resultant array is {2, 3} after removing the 1 from an array. Method 1: Using functionsApproach A: C // C Program to remove All Occurrences of // an element in an array using functions #include <stdio.h> // function declaration int remove_element(int* array, int n, int val) { int i; // iterates array elements for (i = 0; i < n; i++) // if the given array element is not equal to given // value then print array element if (array[i] != val) printf("%d ", array[i]); } int main() { int array[6] = { 1, 2, 1, 3, 1 }, size = 5, value = 1; remove_element(array, size, value); } Output2 3 Approach B: C // C Program to remove all Occurrences of // an element in an array using functions #include <stdio.h> // function declaration int remove_element(int* array, int n, int val) { int i; // iterating the array elements for (i = 0; i < n; i++) { // if array element is equal to the given value then // continue the loop else return the array element if (array[i] == val) { continue; } else { printf("%d ", array[i]); } } } int main() { int array[6] = { 1, 2, 1, 3, 1 }, size = 5, value = 1; remove_element(array, size, value); return 0; } Output2 3 Method 2: Without using functionsApproach A: C // C Program to remove All Occurrences // of an Element in an Array #include <stdio.h> int main() { int array[6] = { 1, 2, 1, 3, 1 }, size = 5, value = 1; int i; // iterating the array elements for (i = 0; i < size; i++) { // if array element is equal to the given value then // continue the loop else return the array element if (array[i] == value) { continue; } else { printf("%d ", array[i]); } } } Output2 3 Approach B: C // C Program to remove all Occurrences // of an Element in an Array #include <stdio.h> int main() { int array[6] = { 1, 2, 1, 3, 1 }, size = 5, value = 1; int i; // iterating the array elements for (i = 0; i < size; i++) { // if array element is equal to the given value then // continue the loop else return the array element if (array[i] != value) { printf("%d ", array[i]); } } } Output2 3 Comment More infoAdvertise with us Next Article C Program to Remove All Occurrences of an Element in an Array L laxmigangarajula03 Follow Improve Article Tags : C Programs C Language C Array Programs Similar Reads C Programming Language Tutorial C is a general-purpose mid-level programming language developed by Dennis M.

The word polymorphism means having many forms, and it comes from the Greek words poly (many) and morph (forms), this means one entity ca 7 min read Dynamic Memory Allocation in C using malloc(), calloc(), free() and realloc() In C, a variable defined in a function is stored in the stack memory. The requirement of this memory is that it needs to know the size of the data to memory at compile time (before the program runs). Also, once defined, we can neither change the size nor completely delete the memory.To resolve this, 9 min read 3-Phase Inverter An inverter is a fundamental electrical device designed primarily for the conversion of direct current into alternating current .
