Replace any space ' ' with '_' in 2-character string passCode. Sample output for the given program:

1_

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

int main() {
string passCode;

passCode = "1 ";

/ Your solution goes here /

cout << passCode << endl;
return 0;
}

The answer is :


for(unsigned int i = 0; i < passCode.length(); i++){
if(isspace(passCode.at(i))){
passCode.at(i) = '_';
}
}
