How to compare char variables (c-strings)?

Question

#include 
using namespace std;

int main() {
    char word[10]=\"php\";
    char word1[10]=\"php\";

    if(word==word1){
        cout<<\"word          


        

Answer 1

Use strcmp.

#include <cstring>
// ...
if(std::strcmp(word, wordl) == 0) {
// ...
}

Answer 2

word and word1 in your submitted code are pointers. So when you code:

word==word1

you are comparing two memory addresses (which isn't what you want), not the c-strings they point to.

Answer 3

Use std::string objects instead:

#include <iostream>
#include <string>
using namespace std;

int main() {
    string word="php";
    string word1="php";

    if(word==word1){
        cout<<"word = word1"<<endl;
    }

return 0;
}

Answer 4

To justify c++ tag you'd probably want to declare word and word1 as std::string. To compare them as is you need

if(!strcmp(word,word1)) {

Answer 5

#include <iostream>
**#include <string>** //You need this lib too

using namespace std;

int main() 
{

char word[10]="php";
char word1[10]="php";

**if(strcmp(word,word1)==0)** *//if you want to validate if they are the same string*
    cout<<"word = word1"<<endl;
*//or*
**if(strcmp(word,word1)!=0)** *//if you want to validate if they're different*
    cout<<"word != word1"<<endl;

return 0;``
