what is wrong with my c program

Question

hello, this program compiles but at the execution something is wrong when I use quotation marks to replace apostrophes it works properly can someone explain why this issue?

#include <stdio.h>

int main() {
int i=5,j=3,k;
i++;
j+=i;
k=++j;
printf('i= %d;j= %d;k= %d',i,j,k);
return 0;
}

Answer 1

You can use single quote only for declare literal chars (eg a single char) while yoi have to use double quote for declare literal strings... Ex:
'c' is different from "c". The first is a character the second is a string builded up by character c followed by implicit null character '\0'.
You cannot declare a string using single-quote char but only a single char
