C string output to null-CodePudding

So I have this code here to take three input from the user, one integer type and 2 character types:

#include <stdio.h>

int main() {

    int carNumber;
    char customerName, carCode;

    printf("Enter Car Number: ");
    scanf("%d", &carNumber);
    printf("Enter Customer Name: ");
    scanf("%s", &customerName);
    printf("Enter Car Code: ");
    scanf("%s", &carCode);

    if (carCode == 'T'){
        printf("Toyota");
    }
    else if (carCode == 'H'){
        printf("Honda");
    }

    printf("\nCar Number: %d", carNumber);
    printf("\nCustomer Name: %s", customerName);
    return 0;

}

While most of it outputs correct, the customerName always prints (null).

CodePudding user response：

To print a character, its " %c" and not "%s". Either use :

char customerName[30];
printf("Customer Name: %s", customerName);

char customerName;
printf("Customer Name: %c", customerName);

Here is your entire program :

#include <stdio.h>

int main()
{
    int carNumber;
    char carCode;
    char customerName[30];

    printf("Enter Car Number: ");
    scanf("%d", &carNumber);
    printf("Enter Customer Name: ");
    scanf("%s", customerName);
    printf("Enter Car Code: ");
    scanf(" %c", &carCode);

    if (carCode == 'T'){
        printf("Toyota\n");
    }
    else if (carCode == 'H'){
        printf("Honda\n");
    }

    printf("Car Number: %d\n", carNumber);
    printf("Customer Name: %s\n", customerName);
     printf("Car Code: %c\n", carCode);
    return 0;
}
