Bug 354098

Description stephen weber 2011-08-07 16:22:56 EDT

Build Identifier: Helios 3.6.1

Given the original program from "C Programming :A Modern Approach" using printf and scanf , all the requests for inputs from scanf's need to be added before all of the printf's are dumped to the console in Eclipse. 
 The obvious solution is to use fflush as for example bug code Bug 173732 wrote 4 years ago. 
Hoping this gnat detail can be fixed some day ;)

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

int main(void) {

	int num1,denom1,num2,denom2,result_num,result_denom;


 printf ("Enter first fraction :");


 scanf("%d/%d",&num1,&denom1);

 printf("Enter second fraction :");
 
 scanf("%d/%d",&num2,&denom2);

result_num=num1*denom2+num2*denom1;
result_denom=denom1*denom2;
printf("The sum is %d/%d\n",result_num,result_denom);
 

	return 0;
}


output "
3/4
4/5
Enter First Fraction :Enter Second Fraction :The Sum is 12/20

needs:




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

int main(void) {

	int num1,denom1,num2,denom2,result_num,result_denom;


 printf ("Enter first fraction :");
 fflush(stdout);

 scanf("%d/%d",&num1,&denom1);

 printf("Enter second fraction :");
 fflush(stdout);
 scanf("%d/%d",&num2,&denom2);

result_num=num1*denom2+num2*denom1;
result_denom=denom1*denom2;
printf("The sum is %d/%d\n",result_num,result_denom);
fflush(stdout);

	return 0;
}


output:
Enter First Fraction:3/4
Enter Second Fraction :4/5
The Sum is 12/20
