Thread: C equivalent of BASIC's STRING$(80,"char")

I am looking for the equivalent in C of BASIC's STRING$(80,"char") ie printing out a string of 80 same characters aaaaaaaa...etc

I found the following code in Rosetta Code, but it comes up with an error
"invalid conversion from 'void*' to 'char*' [-fpermissive].

I have no idea what this means. Can someone enlighten me please?

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
 
char * char_repeat( int n, char c ) {
  char * dest = malloc(n+1);
  memset(dest, c, n);
  dest[n] = '\0';
  return dest;
}
 
int main() {
  char * result = char_repeat(5, '*');
  puts(result);
  free(result);
  return 0;
}
