Question

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

int main()
{
    int T;
    char J[100], S[100];
    int count=0;
    cin >> T;

    while(T--)
    {
        cin.getline(J,100);

        cin.getline(S,100);
        puts(J);
        puts(S);

        for(int i=0; J[i]!='\0'; i++)
        {
            for(int j=0; S[j]!='\0'; j++)
            {
                count++;
                for(int k=j; S[k]!='\0'; k++)
                    S[k]=S[k+1];
                break;
            }
         }
         cout << count;
    }
    return 0;
}

I am taking input string in J,S but during execution of program it skips the second input from the console cin.getline
I takes the test cases then takes the Strings J and S
it takes J successfully but fails to get S string ?

Answer 1

you need to be using a string , std::string, and calling getline as in

std::string s,j;
std::getline(std::cin,j);
std::getline(std::cin,s);

and then if you want to iterate over the contents of the strings by individual characters

for(auto i = std::begin(s); i != std::end(s); ++i)
{
     std::cout << *i << std::endl;
}

use the iterators, and deference them to get the actual character values. Stay way from c strings as much as possible.
