C Programming: Copy one string into another string

C String: Exercise-8 with Solution

Write a program in C to copy one string to another string.

Sample Solution:

C Code:

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


void main()
{
    char str1[100], str2[100];
    int  i;

       printf("\n\nCopy one string into another string :\n");
       printf("-----------------------------------------\n"); 	
       printf("Input the string : ");
       fgets(str1, sizeof str1, stdin);
	   
    /* Copies string1 to string2 character by character */
    i=0;
    while(str1[i]!='\0')
    {
        str2[i] = str1[i];
        i++;
    }

    //Makes sure that the string is NULL terminated
    str2[i] = '\0';

    printf("\nThe First string is : %s\n", str1);
    printf("The Second string is : %s\n", str2);
    printf("Number of characters copied : %d\n\n", i);
}

Sample Output:

Copy one string into another string :                                                                         
-----------------------------------------                                                                     
Input the string : This is a string to be copied.                                                             
                                                                                                              
The First string is : This is a string to be copied.                                                          
                                                                                                              
The Second string is : This is a string to be copied.                                                         
                                                                                                              
Number of characters copied : 31
