Im trying to make it output a username that starts with thefirst 5 letters of their last name, 1st letter of their first name,and last 2 digits and of whatever 4 digit number is input.
like if - Michael Jordan 1991
is input, the output is -
What im struggling with is getting the last 2 digits added,tried for loops but for some reason i couldn't get it to work.
this is what i have
#include <stdio.h>#include <string.h>
int main() {
char firstName[50]; char firstName2[5]; char lastName[50]; char lastName2[5]; int digits[5]; int digits2 = 0; scanf("%s", firstName); scanf("%s", lastName); /* for (int i = 0; i < 4; i++) { scanf("%d", &digits); }*/ strncat(firstName2, firstName, 1); strncat(lastName2, lastName, 5); printf("Your login name: %s%s%d", lastName2, firstName2,digits[ ]);
return 0;}
