How to repeat a char using printf?

Question

I\'d like to do something like printf(\"?\", count, char) to repeat a character count times.

What is the right format-string to accomplish

Answer 1

#include 
#include 

void repeat_char(unsigned int cnt, char ch) {
    char buffer[cnt + 1];
    /*assuming you want to repeat the c character 30 times*/
    memset(buffer,ch,cnd); buffer[cnt]='\0';
    printf("%s",buffer)
}
