Vs code don't ask for input

[Anupam11421]

#include<iostream>
using namespace std;

void spiralprint(int a[][1000],int m,int n){
    int startRow = 0;
    int startCol = 0;
    int endRow = m-1;
    int endCol = n-1;

    while(startRow<=endRow and startCol<=endCol){
        //First Row
        for(int i=startCol;i<=endCol;i++){
            cout<<a[startRow][i]<<" ";
        }
        startRow++; 

        //endCol
        for(int i = startRow;i<=endRow;i++){
            cout<<a[i][endCol]<<" ";
        }
        endCol--;

        //Bottom Row
        for(int i=endCol;i>=startCol;i--){
            cout<<a[endRow][i]<<" ";
        }
        endRow--;

        //startCol
        for(int i = endRow;i>=startRow;i--){
            cout<<a[i][startCol]<<" ";
        }
        startCol++;
    }
}

int main(){
    int a[1000][1000]={0};
    int m , n;

    cout << "Enter m and n: "<<flush;   // ✅ yaha koi problem nahi hai
    cin >> m >> n;

    //Iterate over the array
    int val = 1;
    for(int row = 0; row<=m-1;row++){
        for(int col = 0; col<=n-1;col++){
            a[row][col] = val;
            val = val+1;
            cout<<a[row][col]<<" ";
        }
        cout<<endl;
    }

    spiralprint(a,m,n);

    return 0;
}

this is what i get

why it don't ask for input even don't ask for Enter the value of m and n even i do cout still didn't
i have done this all from chatgpt and perplexity but i'm not able to resolve the problem 1st thing that i tell you that i know how to run the program in vs code just asking why it get terminated automaticaaly

This works for me. Did you follow our guide for GCC on Windows? https://code.visualstudio.com/docs/cpp/config-mingw.

The most likely suspect is that the PATH environment variable is not updated to point to the dll's that MinGW depends on so the program fails to run and exits immediately. You'll know it's working if you see the first message printed out: "Enter m and n:"

i don't know it don't help me actually i try other problem like checking palindrome

// read a sentence/paragraph  and check if it's palindrone or not 
#include<iostream>
#include<cstring>
using namespace std;

bool ispalindrome(char a[]){
    int i = 0;
    int j = strlen(a)-1;

    while(i<j){
        if(a[i]==a[j]){
            i++;
            j--;
        }
        else{
            return false;
        }
    }
    return true;
}

int main()
{
    char a[1000];
    cin.getline(a,1000);
    if(ispalindrome){
        cout<<"palindromic string";
    }
    else{
        cout<<"Not a palindrome";
    }

 return 0;
}

this program run fine asking or say wait for my input but that spiralprint.cpp program i don't know what happen to it

C:\Users\ASUS\Desktop\The PG folder\c++>cd Array

C:\Users\ASUS\Desktop\The PG folder\c++\Array>g++ palindrome.cpp -o palindrome.exe

C:\Users\ASUS\Desktop\The PG folder\c++\Array>.\palindrome.exe
abba
palindromic string

I managed to reproduce the issue with sprialprint on another computer. The program crashes on startup (segmentation fault). I don't know why the program fails (maybe Windows does not allow you to allocate that much data on the stack in programs compiled by this compiler), but I lowered the size of the arrays being allocated and then it worked fine. It's possible there is a compiler flag that will let you specify a larger stack size.
