How to take first letter from C string?

Question

I want to take the first letter from my firstname string variable and add it to the second letter of the lastname variable.

My program so far is:

#include <stdio.h>

main() {
char firstname [256];
char lastname [256];
printf("What's your first name?: ");
scanf("%c",&firstname);
printf("What is your last name? ");
scanf("%s",&lastname);
printf("\nYour school.edu e-mail address is: %c%[email protected]",firstname,lastname);
return 0;
}

However, I would like for my code to take the first initial (the first letter of the first name) and store it into the firstname variable.

Answer 1

As strings are array of characters, you need to take the first element from the array:

char firstname_initial;
firstname_initial = firstname[0]

Also note that since lastname and firstname are buffers, you don't need to pass a pointer to them in scanf:

scanf( "%s", firstname );
scanf( "%s", lastname );

And one last thing - scanf is a dangerous function and you should not use it.
