Decimal Problem In C
 |
Hi everyone,
Some questions in my previous post is still left unanswered.
Here it is again:
How can i accept decimal numbers from STDIN and perform arithmetic operations on it in C.
How can i create a subroutine within a program, that can be called again & again at different part of a program.
THANKS :mrgreen:

Hi everyone,
I not very clear what you are talking about.
Receving decimal numbers???
Do you mean returning decimal numbers from a function
declare a variable as float
float a;
a = rew( ); // Is this what you mean
As for your other question
You cannot call a function within its own function.
You can declare the function externally being public or private
and call it
if there is arguments and a return value
a = gow(c,d); // Is this what you mean
if it has no arguments or any return values
gow(); //Is this what you mean
I really hope this helps you
Yours Sincerely

For reading you use scanf() with format specifier "%f","%g","%e" or printf();
the variable tyoe is float and functions are in math.h
You need functions->read tutorials

OK, let me clear things up, suppose i want to enter 23.45 using SCANF, the program will only accept the 23 and use the .45 for the other SCANF, how can i avoid it.

First, avoid scanf. Second, use a floating point type to enter a floating point value.
#include <stdio.h>
int main()
{
double number;
fputs("Enter number: ", stdout);
fflush(stdout);
if ( scanf("%lf", &number) == 1)
{
printf("number = %g\n", number);
}
return 0;
}
/* my output
Enter number: 23.45
number = 23.45
