Video Tutorial illustrating: C Program To Calculation of Simple Interest.
Header File:
#include<stdio.h> |
To be able to use printf function, we have to include stdio.h header file.
main()
This is the starting point of C program execution.
since it does not return any value, we write void main()
Declaration of Variables:
int p, n; float r, si; |
variables p and n are integer type variables i.e., they can hold integer values.
variables r and si are float or real type variables i.e., they can hold fractional values.
clrscr(); |
to clear the output screen.
Initialization of Variables:
p = 1000; n = 3; r = 8.5; |
Principle p = 1000
n or time or duration = 3
rate of interest r = 8.5
Formula to calculate simple interest:
si = ( p * n * r ) / 100; |
The mathematical formula si = ( p x n x r ) / 100; is written as si = ( p * n * r ) / 100;
Output statement:
printf("%f\n",si); |
the function printf is present inside stdio.h header file. %f is formatting string for float or real type values.
getch(); |
function to return to the console window.
