what is wrong with this print_repeat function?

print_repeat should print out the string s, but repeat the ith character i times (starting counting at 1).

So print_repeat("this") should print thhiiissss

int print_repeat(char s[]){
    int i,j;

     i = 0;
     while (s[i] != '\0');{
         for (j = 1; j <= i+1; j+1){
             putchar(s[i]);
         }
    }

}

void main()
{
    print_repeat("this");
}

Find the correct code below:

    while (s[i] != '\0')
    { 
      for (j = 1; j <= i+1; j++)
      { 
        putchar(s[i]); 
      } 
     i++;
   } 

The main problems were: 1. Not incrementing the variable i inside while loop 2. Variable j is not incremented correctly 3. There is semicolon right after the while which is incorrect.

Suggestion: try debugging your code. That will help you learn faster.

In your print_repeat code, you never increment i in your while loop, which would result in infinite loops.

add "i++;" on the end of the while loop.
