当您从 cmd 文件运行 C 程序时，程序工作一半

Question

I was coding a C program that gives us the area of sphere and circle. You put inputs and than it calculates. But there is a problem. I have done this project for pi day and I must send it to someone. When I open the program from exe file it can only go for circle and spehere's radius input part. When you input something, it closes itself. When I run it from Dev C++ there isn't any problem. What is wrong with exe file?

    #include <stdio.h>
    #include <conio.h>
    #define PI 3.14159265
    
    /* run this program using the console pauser or add your own getch, system("pause") or input loop */
    
    int main() {
        getch();
        char bilgi;
        printf("Kurenin hacmini mi yoksa dairenin alanini mi hesaplamak istersiniz?\n");
        printf("Daire icin girdi kismina d, kure icin k yaziniz:");
        scanf("%c", &bilgi);
            if(bilgi == 'k') {
                    float yaricap;
        float hacim;
        printf("Merhaba, bu fonksiyon kure hacmini hesaplamak icin tasarlanmistir.\n");
        printf("Lutfen kurenin yaricapini giriniz:");
        scanf("%f", &yaricap);
        hacim = (4.00*3.00)*PI*(yaricap*yaricap*yaricap);
        printf("Kurenin hacmi %f", hacim);
                return 0;
    
            } else if(bilgi == 'd'){
        getch();     
        float yaricapdaire;
        float alan;
        printf("Bu fonksiyon dairenin alanini hesaplamak icin tasarlanmistir.\n");
        printf("Lutfen dairenin yaricapini giriniz:");
        scanf("%f", &yaricapdaire);
        alan = PI*(yaricapdaire*yaricapdaire);
        printf("Dairenin alani %f", alan);
                
            return 0;       
                
            }
    
        return 0;
    }

Answer 1

I fixed it. Putting a getch(); before every return 0; fixed it.
