How to combine arrays in c++?

Question

There are two character arrays, for example a{'a','b','c'} and b{'d','e','f'}, you need to get an array c{'a','b','c','d','e','f'} ,how can I do this?

Answer 1

#include <iostream>
#include <cstring>
using namespace std;
#define SIZE 100

int main() {
char a[SIZE] = {'a','b','c'};
char b[SIZE] = {'d','e','f'};
char c[SIZE] = {};

size_t i;
for(i=0; i<strlen(a); i++) c[i] = a[i];
for(i=0; i<strlen(b); i++) c[i + strlen(a)] = b[i];

cout << c << endl;
return 0;
}

// Keep learning & happy coding :D

Answer 2

SoloProg good solution.

Alternative way using C string functions:
strcpy(c, a);
strcat(c, b);
cout << c << endl;

Pranshu Sachan ,

I don't know about your code show me your code in a correct way.

👍👍

Answer 5

SoloProg i think size(c) >=size(a) +size(b).
If we want to accumulate all value of a and b into c
