C program to copy one string into another.

#include<stdio.h>

void main()
{
       int i;
       char str1[50],str2[50];
       clrscr();

       printf("Enter first string: ");
       scanf("%s",&str1);

       printf("Enter second string: ");
       scanf("%s",&str2);

       strcpy(str1,str2);

       printf("First string is: %s",str1);
       getch();

}

C program to copy one string into another without string function

                                           To copy one string into another without using string handling function loop will be continue till the last character of the second string. and after completing loop the last character must be initialize with the null value.

#include<stdio.h>
#include<conio.h>

void main()
{
       int i;
       char str1[50],str2[50];
       clrscr();

       printf("Enter first string:");
       scanf("%s",&str1);

       printf("Enter second string:");
       scanf("%s",&str2);

       for(i=0;str2[i]!='\0';i++)
       {
              str1[i]=str2[i];
       }

       str1[i]='\0';

       printf("first string is : %s",str1);
       printf("\nSecond string copy into first one");

       getch();
}
