C Program to read two Strings & Concatenate the Strings

#include < stdio.h>
#include < string.h>
 
void main()
{
    char string1[20], string2[20];
    int i, j, pos;
 
    /*  Initialize the string to NULL values */
    memset(string1, 0, 20);
    memset(string2, 0, 20);
 
    printf("Enter the first string : " );
    scanf("%s" , string1);
    printf("Enter the second string: " );
    scanf("%s" , string2);
    printf("First string  = %s\n" , string1);
    printf("Second string = %s\n" , string2);
 
    /*  Concate the second string to the end of the first string */
    for (i = 0; string1[i] != '\0'; i++)
    {
        /*  null statement: simply traversing the string1 */
        ;
    }
    pos = i;
    for (j = 0; string2[j] != '\0'; i++)
    {
        string1[i] = string2[j++];
    }
    /*  set the last character of string1 to NULL */
    string1[i] = '\0';
    printf("Concatenated string = %s\n" , string1);
}

Output

 Enter the first string : San
Enter the second string: foundry
First string  = San
Second string = foundry
Concatenated string = Sanfoundry
