Question

using C programming

Compose a program that declares two string arrays that are 81 characters in size. Prompt the user to enter in a string and store it in array 1. Construct a function that returns a void and takes both arrays as parameters and copies array 1 into array 2 using sizeof() to ensure that the size does not exceed the destination array. Back in the caller print the second array to show that the function worked.

NOTE: We are using the copy function inside a copy function. This is redundant but I want you to practice passing arrays and writing functions.

Answer 1

#include<stdio.h>

void stringCopy(char array1[81], char array2[81]){
   int i;
   for(i=0;array1[i]!='\0';i++){
      array2[i] = array1[i];
   }
   array2[i] = '\0';
}

void main () {
   char array1[81], array2[81];
   printf("Enter string: ");
   scanf(" %[^\t\n]s",&array1);
   stringCopy(array1,array2);
   printf("Array2 = %s\n",array2);
   return 0;
}
