Question

Please program in c. Must be in c and not c++.

Write a program that prompts for the user's first and last names. Declare a third array that will hold the user's last name and first name, separated by a comma and space. Use loops to inter through the names one character at a time, storing them into the full name array. Don't forget about the terminating character.
Sample run:
Enter your first name: jinan
Enter your last name: fiaidhi
First name: Jinan
Last name: Fiaidhi
Full name: Fiaidhi, Jinan

Answer 1

//CODE

#include<stdio.h>
int main(int argc, char const *argv[])
{
   //Declaring Arrays
   char first[50],last[50],names[50][50];
   //Getting inputs from user
   printf("Enter your First Name :");
   scanf("%s",first);
   printf("Enter your Last name :");
   scanf("%s",last);
   //initializing variables
   int i=0,j=0,k=0;
   //copying last name to names array using loop
   while(last[j]){
       names[i][k++]=last[j++];
   }
   //Inserting , and ' ' characters
   names[i][k++]=',';
   names[i][k++]=' ';
   j=0;
   //Inserting first name to names array using loop
   while(first[j]){
       names[i][k++]=first[j++];
   }
   //Inserting terminating character
   names[i][k]='\0';
   //Printing the results.
   printf("First name:%s\n",first);
   printf("Last name:%s\n",last);
   printf("Full name :%s\n",names[i]);
   return 0;
}

//OUTPUT
