Studi Kasus

Pemecahan masalah untuk menghitung, dibawah ini script untuk kalkulator pada bahasa pemrograman C  , monggo di coba brosis

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

int main() 
{ printf("================================================\n");
printf("STMIK Bina Insani\n"); printf("================================================\n");
printf("Notria Fajar Prasetya\nTI-14A\n"); printf(" Calculator \n"); printf("================================================\n");
printf(" \n");
printf(" \n");
int valid_operator =1;
char operator;
float Number1,Number2,result; printf("Masukkan 2 Bilangan yang Diinginkan\n");
printf(" \n");
start:
scanf("%f %c %f", &Number1, &operator, &Number2);
if (operator == '*')
result = Number1*Number2;
if (operator == '/')
result = Number1/Number2;
if (operator == '+')
result = Number1+Number2;
if (operator == '-')
result = Number1-Number2;
if (valid_operator);
printf("=%g",result);

char pilih;
fflush (stdin);
printf("menghitung lagi ? \n");
printf("Y\nT\n");
scanf("%c",&pilih);

if(pilih=='Y')
goto start;
else stop:
if(pilih=='T')
else
goto stop;

return 0;
}
