July 30, 2022

I keep getting the same error when I try to compile it

#include <stdio.h>

int main(){

    char name[25];
    int age;

    printf("\nwhat is your name: ");
    scanf("%s", &name);

    printf("what is your age: ");
    scanf("%d", &age);

    printf("\nyour name is %s", name);
    printf("\nand your age is %d", age);

    return 0;
}

>Solution :

I assume this is the "error" you are receiving:

main.c: In function 'main':
main.c:9:9: warning: format '%s' expects argument of type 'char *', but argument 2 has type 'char (*)[25]' [-Wformat=]
 scanf("%s", &name);

You should try to read and understand it, as compiler warnings usually are quite clear. This one tells you that the %s in the line scanf("%s", &name); expects a char *, that is, a pointer to a char, whereas you have supplied a char (*)[25] which is a pointer to an array of 25 chars.

Basically, the argument &name has the wrong type. The name of the array, in this case the name is a pointer to the first element of the array, and you should not put an ampersand (&) (the address of …) operator when giving it as an argument to scanf.

The correct call would be: scanf("%s", name);.

I also strongly suggest you to avoid using scanf as a user-interface function. See this.
