C Exercises: Remove all instances of a given value in a given array of integers and return the length of the new array
C Programming Practice: Exercise-13 with Solution
Write a C programming to remove all instances of a given value in a given array of integers and return the length of the new array.
C Code:
#include <stdio.h>
#include <stdlib.h>
static int removeElement(int *nums, int arr_size, int val)
{
int i, ctr = 0;
for (i = 0; i < arr_size; i++) {
if (nums[i] != val) {
nums[ctr++] = nums[i];
}
}
return ctr;
}
int main(void)
{
int nums[] = {1,1,2,3,4,4,5,6,6,6};
int size = sizeof(nums)/sizeof(nums[0]);
printf("Original array:\n");
int i;
int val = 4;
for (i = 0; i < size; i++) {
printf("%d ", nums[i]);
}
int new_size = removeElement(nums, size, val);
printf("\nSize of the new array after removing the value 4: %d\n",new_size);
return 0;
}
Sample Output:
Original array: 1 1 2 3 4 4 5 6 6 6 Size of the new array after removing the value 4: 8

Maximum value of int:
In C:
#include <limits.h> then use int imin = INT_MIN; // minimum value int imax = INT_MAX;
or
#include <float.h> float fmin = FLT_MIN; // minimum positive value double dmin = DBL_MIN; // minimum positive value float fmax = FLT_MAX; double dmax = DBL_MAX;
