Thread: Lining up my Array

Hello, I am a fresh newbie of C programming and I am having some trouble with a problem.

When you execute this it prints it as: (assuming you use 'Name' as the first name and Lastname as the last name)

Name LastName
4 8


The counts need to be aligned with the beginning of each name. The 4 under N and the 8 under the L.

This is what I came up thus far.

Code:

#include <stdio.h>
#include <string.h>
#include <stdlib.h>


int main(){
        char Name[10];
        char LastName[10];

        printf("What is your first name?: ");
        scanf("%s", Name);
        printf("What is your last name?: ");
        scanf("%s", LastName);
        printf("%s %s\n %d %d ", Name, LastName,
               strlen(Name), strlen(LastName), sizeof Name, sizeof LastName);

        return 0;
}

Any sort of feedback is welcomed.

so %*d aligns it?
and why did you put strlen(Name) Twice?
I guess I didn't have to put the sizeof functions either.

sorry for the extra questions but I'd like to know why it works.

Thank you Aia.

thanks for the info.

Code:

#include <stdio.h>
#include <string.h>
#include <stdlib.h>


int main(){
        char Name[10];
        char LastName[10];

        printf("What is your first name?: ");
        scanf("%s", Name);
        printf("What is your last name?: ");
        scanf("%s", LastName);
        printf("%s %s\n %d %d ", Name, LastName,
               strlen(Name), strlen(LastName), sizeof Name, sizeof LastName);

        return 0;
}
