I can't understand why this simple code, that is storing an answer from the user is giving me back this error.

• I would like to save the answer into a variable q_ai and be able to use this variable in an if.

this below is my code:

//INPUT TRY 0
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

//setting game:
char q_ai;      //want to play against ai? question about ai.


int main(void)
{   

    printf("Do you want to play vs AI? \n   Y/N? \n ");
    scanf("%c",q_ai);       
    printf("q_ai == %c\n",q_ai);
    printf("sizeof(q_ai): %d",sizeof(q_ai));
    
    if(q_ai=="y") {
        printf("you will play against AI");
    }
    
    if(q_ai=="n") {
        printf("you will play 1v1");
    }
    
    
}

How can I solve this problem? thanks

CodePudding user response：

What you have right now is comparing a character to pointers to strings ("y" and "n"). You need to compare the character q_ai to characters ('y' and 'n').

if(q_ai=='y') {
    printf("you will play against AI");
}

if(q_ai=='n') {
    printf("you will play 1v1");
}
