Thread: quiz program

What's wrong with this code? When I run it, it first prints the first question, I enter a character (the answer - a or b or c or d), then prints the second question and immediately prints the third question. I can't enter the answer for the second question as well as for the fourth. The code literally jumps over those statements and I don't get why. I get no errors but this works wrong.

Code:

#include <stdio.h>
#include <conio.h>


int points(char,char,char,char,char);


char c1='c', c2='b', c3='b', c4='d', c5='a';


int main() {
    char a1, a2, a3, a4, a5; int count;


    printf("Q1 :Which of the following is a greenhouse gas that is ");
    printf("released by human activities and speeds up global warming?\n");
    printf("a: petroleum\nb: natural gas\nc: carbon dioxide\nd: nuclear power\n\n"); // carbon dioxide
    printf("Your answer: \n\n"); scanf_s("%c",&a1);


    printf("Q2: Which of the following human activities does NOT release carbon dioxide into the atmosphere?\n");
    printf("a: burning fossil fuels\nb: fishing\nc: deforestation\nd: driving\n\n"); // fishing
    printf("Your answer: \n\n"); scanf_s("%c",&a2);


    printf("As global warming continues, the intensity of what type of ");
    printf("storm that hits coastlines is predicted to increase?");
    printf("a: tornadoes\nb: hurricanes\nc: tsunamis\nd: earthquakes\n\n"); // hurricanes
    printf("Your answer: \n\n"); scanf_s("%c",&a3);


    printf("Q4: Rising water temperatures is a result of global warming and may eventually ");
    printf("increase sea levels due to the dissolving of what?\n");
    printf("a: mountains\nb: wetlands\nc: river beds\nd: glaciers\n\n"); // glaciers
    printf("Your answer: \n\n"); scanf_s("%c",&a4);


    printf("What country emits the most carbon dioxide?\n");
    printf("a: China\nb: United States\nc: Russia\nd: India\n\n"); // China
    printf("Your answer: \n\n"); scanf_s("%c",&a5);


    count=points(a1,a2,a3,a4,a5);
    printf("YOUR SCORE: %d out of 5\n", count);
    switch(count) {
        case 5: printf("Excellent\n");
        case 4: printf("Very good\n");
        case 3: printf("Time to brush up on your knowledge of global warming.\n");
    }
    _getch();
    return 0;
}


int points(char a1,char a2,char a3,char a4,char a5) {
    int count=0;
    if (a1==c1) {count++;}
