VScode Debugger output not shown-CodePudding

So I just Started Learning to code but VS code is acting weird ?

When i run my code in Debug mode the code sometimes does not work. The code react differently when i ask for "user input" VS "NOT asking for User Input".

CODE - "NOT asking for User Input"

#include <stdio.h>
#include <stdlib.h>

int main(){
    enum Company {
        Google,
        FaceBook,
        XEROX,
        YAHOO,
        EBAY,
        Microsoft
    }COMPANY;
    // int test;
    // scanf("%i", test);
    // printf("%i",test);

    COMPANY = Google;
    printf("%d\n", COMPANY);

    int i;
    for (i= Google; i <= Microsoft; i  )
    {
        printf("%i\n", i);
    };
    return 0;
}

Output Image of the Debug Console

CODE - "user input"

#include <stdio.h>
#include <stdlib.h>

int main(){
    enum Company {
        Google,
        FaceBook,
        XEROX,
        YAHOO,
        EBAY,
        Microsoft
    }COMPANY;
    int test;
    scanf("%i", test);
    printf("%i",test);

    COMPANY = Google;
    printf("%d\n", COMPANY);

    int i;
    for (i= Google; i <= Microsoft; i  )
    {
        printf("%i\n", i);
    };
    return 0;
}

Output: Output for debug console

CodePudding user response：

scanf("%i", test);

should be

scanf("%i", &test)

scanf() expect a pointer to int, but you're passing an int instead.

CodePudding user response：

besides the syntax error in the call to scanf()

when you enter some value, you have to also enter a 'enter' key so the number is passed through the terminal to the program.
