Answer 1

#include <stdio.h>
#include <string.h>
 
int main() {
    char str[] = "abc123def";
     
    int mid = strlen(str) / 2;
    int N = 3;
     
    // void *memmove(void *dest_str, const void *src_str, size_t numBytes)
    // + 1 at the end is for the null
    memmove(&str[mid - N / 2], &str[mid + 1 + N / 2], strlen(str) - (mid + 1 + N / 2) + 1);
 
    printf("%s\n", str);
