How can I make a char into a string

Question

Hello! I was wondering how could I make 'y' and 'n' into yes and no because i tried it and it wasn't working. I wrote the following code:
#include <stdio.h>
#include <stdlib.h>
int main(){
int age;
char unemployed;
printf("how old are you?\n");
scanf("%d",&age);
if(age>0 && age<18){
printf("ticket price is 10€");
}
else if(age>18) {
printf("are you unemployed\n");
scanf(" %c",&unemployed);
if(unemployed=='y'){
printf("your ticket price is 8 euros");
}
else if(unemployed=='n'){
printf("your ticket price is 20€ euros");
}
}
return 0;
}

Answer 1

//Make a char array
char unemployed[4];

//input in array
scanf("%s", unemployed);

//compare them using strcmp function
if(strcmp(unemployed, "yes") == 0)
//true statement
else if(strcmp(unemployed, "no") == 0)
//false statement

Remember:
strcmp function returns 0 only if both arrays are equal and it is defined in the string.h library (not sure)
