Answer 1

#include <stdio.h>
#include <string.h>
 
void remove_all_occurrences(char *s, int ch) { 
    int j, len = strlen(s); 
     
    for (int i = j = 0; i < len; i++) 
       if (s[i] != ch) 
          s[j++] = s[i]; 
       
    s[j] = '\0'; 
} 
 
int main(int argc, char **argv) 
{
    char s[] = "c programming language"; 
     
    remove_all_occurrences(s, 'a');
