String concatenation in c without using string functions

#include<stdio.h>

void stringConcat(char[],char[]);

int main(){

    char str1[100],str2[100];

    int compare;

    printf("Enter first string: ");

    scanf("%s",str1);

    printf("Enter second string: ");

    scanf("%s",str2);

    stringConcat(str1,str2);

    printf("String after concatenation: %s",str1);

    return 0;

}

void stringConcat(char str1[],char str2[]){

    int i=0,j=0;

   

   

    while(str1[i]!='\0'){

         i++;

    }

    while(str2[j]!='\0'){

         str1[i] = str2[j];   

         i++;

         j++;

    }

    str1[i] = '\0';

}

Sample output:

Enter first string: ctechnotips

Enter second string: @blogspot.com

String after concatenation: ctechnotips@blogspot.com
