Logic Error (Simple IF Statement)

[1991dan]

I have the following block of code...

       int counter2 = 0;

       while(counter2 <  1) {

        printf("What time of the day were you travelling at? Was it at the peak
                scanf("%d", &timeofday);

        if(timeofday == 1 || timeofday ==2) {
                counter2 = counter2 + 1;
                                                                 }
        else
                printf("ERROR; incorrect input.");

                                         }

I wanted to keep prompting the user for this question until the integer "1" is entered. I don't think the IF statement is ever true regardless if I were to enter a 1, or not. Simply because I am comparing the input from the user with an integer, which i believe is the problem. But.. how would i be able to fix this?

1. parse the input to get an integer
2. compare string to string, something like

 if(timeofday == "1" || timeofday == "2") {

 if(timeofday == "1" || timeofday == "2") {

When I tried to use the quotations and compare string to string, the compiler said that i was trying to compare between a pointer and an integer.

The code sample appears to be C++ - try the c++ forums not the C# forums.

This is what I have tried to do in my attempt to parse the user input, still generate error.

         int timeParse = 0;
do{

       while(counter2 < 1) {
        printf("What time of the day were you travelling at? Was it at the peak 
                scanf("%d", &timeofday);
                int timeParse = int.Parse(timeofday);


                printf("made it here");
                counter2 = counter2 + 1;
        if(timeParse == 1 || timeParse  == 2){
                counter2 = counter2 + 1;
                                            }
        else{
                printf("ERROR; Please enter a valid input.");
            }
       }

scanf and printf are both C/C++ methods. They don't exist in C#.

Are you trying to write a C# application or a C/C++ application ?

You are aware that they are completely different languages ?

I think the intention is clear, rewrite it to the language you are using. I think that it could be something like

if(timeofday* == "1" || timeofday* == "2")
