you can use strcat function. #include<string.h> main() { char s1[100] , char s2[] = "string 2"; scanf ("%s", s1); strcat(s1,s2); } in s1 string in we have to concatenate, s2 which string is to concatenate. final concatenated string will be s1. [EDIT]: or if you want to implement it from scratch, you can do it using loops.

you can use string function in c , like : strcat() function is used to join two strings, https://www.programiz.com/c-programming/library-function/string.h/strcat

#include <stdio.h> #include <string.h> #include <math.h> #include <stdlib.h> int main() { int i = 4; double d = 4.0; char s[] = "HackerRank "; // Declare second integer, double, and String variables. int a,j=0,k=0; double b; char c[105],s3[105]; // Read and save an integer, double, and String to your variables. scanf("%d\n",&a); scanf("%lf\n",&b); scanf("%s",c); //scanf("%*[^\n]%*c", &c); // Print the sum of both integer variables on a new line. printf("%d\n",i+a); // Print the sum of the double variables on a new line. printf("%.1f\n",d+b); // Concatenate and print the String variables on a new line // The 's' variable above should be printed first. printf("%s",s); printf("%s",c); return 0; }

You must enter an integer a double and a string. It will add the numbers and concatenate the strings. but in this case only first word of the string concatenates the rest don't. please correct it

Naqvi Viyank c doesn't follow the oops concepts, so you can't overload the + operator in c, but yes you can do it in cpp. in python and some other languages, it's already handy given to you.
