C programming failed...

M. Bison, post: 81035, member: 359 Wrote:98+99+88+87+79 = 451 which divided by 500 is less than 1. The datatype is an int which means anything beyond the integer is dropped, making it 0. The result is 0 * 100 = 0.

Try this:
Code:
#include<stdio.h>
int main()
{
int m1,m2,m3,m4,m5,per;
printf("Enter the marks of five subjects\n");
scanf("%d%d%d%d%d",&m1,&m2,&m3,&m4,&m5);
per=(int)(((float)(m1+m2+m3+m4+m5))/500.0*100.0);
if(per>=80)
printf("First Division\n");
else if(per>=60)
printf("Second Division\n");
else if(per>=50)
printf("Third Division\n");
else
printf("Fail");
return 0;
}

PS: If you intend on rounding to the nearest integer, add 0.5 before the cast to int.
THANKS about it MAN!!! THANKS AGAIN!!

An integer does not store anything beyond the decimal. That means it always rounds down.

(int)15.9999 = 15
(int)15.4999 = 15
(int)15.5 = 15
(int)15.1 = 15

Real example: 99+99+99+99+98 = 494 / 500 = 0.988 * 100 = 98.8
(int)98.8 = 98

If you intend on rounding to the nearest integer (whole number) then adding 0.5 remedies this situation:

(int)(15.9999 + 0.5) = 16
(int)(15.4999 + 0.5) = 15
(int)(15.5 + 0.5) = 16
(int)(15.1 + 0.5) = 15

Real example: 99+99+99+99+98 = 494 / 500 = 0.988 * 100 = 98.8
(int)(98.8 + 0.5) = 99

Watch out for negative numbers!

why not just define the number variables as

float m1,m2,m3,m4,m5,per;
be the best version of yourself, that's all you can do.

I was thinking like the same.........

Thanks Bison it worked AND NOW A BIG SALUTE TO PROGRAMMING KING!!Big Grin

Double post

Okay guys moved on to another problem could you get me outta here??
THE CODE:
Code:
#include <stdio.h>
int main()
{
char another;
int num;
do
{
printf("Enter a number");
scanf("%d",&num);
printf("Square of %d is %d\n",num,num*num);
printf("Want to enter another number? y/n");
scanf("%c",&another);
} while(another=='y');
return 0;
}
Now the problem is here
Code:
printf("Enter a number");
scanf("%d",&num);
printf("Square of %d is %d\n",num,num*num);
printf("Want to enter another number? y/n");
scanf("%c",&another);
after this executed
Code:
printf("Square of %d is %d\n",num,num*num);
Nothing HAPPENS IT DOESNT ASK!! Y/N!
I mean the square PROGRAM STOPS!

Here's what is happening: After inputting the number, you're pressing enter. Enter is a newline character and doesn't actually disappear. The subsequent scanf is using the character to terminate the loop.

The easiest solution is to add a space before %c. I've also added some newlines to cleanup your output.

Try this:
Code:
#include <stdio.h>
int main()
{
char another;
int num;
do
{
printf("Enter a number\n");
scanf("%d",&num);
printf("Square of %d is %d\n",num,num*num);
printf("Want to enter another number? y/n\n");
scanf(" %c",&another);
} while(another=='y');
return 0;
}

Why isn't anyone else replying anymore? Rolleyes

Danger, just remember you can't let Bison keep on doing your homework for you.

You have to figure some things out yourself if you want to learn the language better.

i miss programming..too bad i'm too much of a noob to do anything special or unique.
be the best version of yourself, that's all you can do.

GAHHH CHANGE THE 500*100 TO JUST BE 5!


per=(m1+m2+m3+m4+m5)/5;

that was said like 2 times in this thread then you kept going and making it more and more complicated. the /5 is all you need. why were you doing 500 in the first place?
