Since C doesn't have boolean types how could I make the user use yes or no as an answer to an if?

Answer 1

Oh, then it seems you want to input a string. You can use
char unemployed[10];
scanf("%s", &unemployed);

and unemplyed!="no", etc in the relevant places. That should work out, but let me know if it doesn't. My C is a little rusty.

Answer 2

You can use stdbool.h library like Babak said or you can use integers for that too.
int isTrue = 1 //if true
isTrue = 0 //if false

Answer 3

Oh C'mon Kishalaya ! :D
It's not rusty, it's trusty! ;D

MargaritaK include <stdbool.h> header to your code then you have access to

bool
true
false

Answer 4

I'm not sure I understand your question completely, but using the integers 1 and 0 instead of the boolean data types True and False should work.

Answer 5

Thank you very very much! I'll try them out and I'll let you know!:-)

Answer 6

Thank you for answering, I've written this code:
#include <stdio.h>
#include <stdlib.h>
int main (){
int age,unemployed;
printf("how old are you?\n");
scanf("%d",&age);
printf("are you unemployed?\n");
scanf("%d", &unemployed);
if(age<18){
printf("your ticket price is 14 euros"); }
else if((age>18)&&(age<60)&&(unemployed!=0)){
printf("your ticket price is 16 euros");}
else if((age>18)&&(age<60)&&(unemployed==0)){
printf("your ticket price is 13 euros");
}
else if(age>=60){
printf("your ticket price is 13 euros"); }
return 0;}
And on the output of the question "are you unemployed" it only executes the non employed command only if I type 0. I wondered if there was a way to replace 0 with no. Thank you
