Why this is happening

hello friends,

In this quiz code all the quiz score is counting but everytime

it shows the msg "you did ok" even after answering all answers correct

Code:

#include <stdio.h>#include <string.h>






int main(){
int rl,count,i;
int score,score1,score2,score3,score4,score5,score6;
count = 0;
     for(i=0;i<=6;i++){
     system("cls");
     rl = i;


     switch(rl){
   case 1:
    printf("\n\nWhich of the following is Palindrome number?");
    printf("\n\nA.42042\t\tB.101010\n\nC.23232\t\tD.01234");
    if(toupper(getch())=='C'){


       printf("\nCorrect!!!");
       count++;
       score1 = 5;
       getch();
       break;


    } else {


      printf("\nWrong!!! .The correct answer is C.23232");
      score1 =0;
      getch();
      break;
    }


     case 2:
    printf("\n\nThe Country with highest environmental performance index is...?");
    printf("\n\nA.France\t\tB.Denmark\n\nC.Switzerland\t\tD.Finland");
    if(toupper(getch())=='C'){


       printf("\nCorrect!!!");
       count++;
       score2 = 5;
       getch();
       break;


    } else {


      printf("\nWrong!!! .The correct answer is C.Switzerland");
      score2 = 0;
      getch();
      break;
    }


     case 3:
    printf("\n\nWhich animal laughs like human being?");

    }

Please list all numbers greater than 4 that is not greater than 2.

Hint: If using > in this type of if/else statement start with the highest condition check first.

Break up your main functions into smaller functions that each does one thing and does it well.

DRY principle: Don't Repeat Yourself. If you do the same thing in multiple places, try to pull it out to do it in one place. See if you can use loops to reduce duplication, if not typically you can write a function or two.

Generally, you only need one blank line to separate logical sections of code. At top level you might use two or even three blank lines, but four or more blank lines pretty much always merely make the code harder to read.

If you are numbering your variables, consider using an array.

You're indenting your code, which is good, but for indentation to be useful it must be consistent, otherwise it becomes just extra whitespace rather than a guide to the code structure.

Note that getch is non-standard.

this actually worked as stahta said to keep bigger condition first

Code:

#include <stdio.h>#include <string.h>






int main(){
int rl,count,i;
int score,score1,score2,score3,score4,score5,score6;
count = 0;
quiz:

     system("cls");
     rl = i;


     switch(rl){

    printf("\n\nA.42042\t\tB.101010\n\nC.23232\t\tD.01234");
    if(toupper(getch())=='C'){


       printf("\nCorrect!!!");
       count++;
       score1 = 5;
       getch();
       break;


    } else {


      printf("\nWrong!!! .The correct answer is C.23232");
      score1 =0;
      getch();
      break;
    }

@lasrelight ya i know arrays would be the way to go for tht but i am still new in coding so numbered those variables

i will try to keep other points in mind

getch() is not standard? then what to use in place of tht?

By default, input is line-buffered in almost all systems. There is no standard way to get unbuffered input from the user. What you could do instead of asking for any key to be pressed is to ask for enter to be pressed( be careful with stray newlines though ).

It's better to ask the user what they want to do now.

This should get your started - Basically loop until the user enters 'r' to reset, or q for quit

Code:

    printf("\nsorry you need to practice");

    char userInput[BUFSIZ] = {0};

    do
    {
        printf("\nWould you like to (r)estart or (q)uit?: ");
        fflush(stdout);

        fgets(userInput, BUFSIZ, stdin);
    }
    while (!(userInput[1] == '\n' && ((userInput[0] == 'r') || (userInput[0] == 'q'))));
