power function in C

[V Rajagopalan]

By using C program i am trying to calculate compound interest. The principal amount is Rs.1000, Period 2 years, Interest is 10%. When i manually calculate it gives Rs. 1210.00. whereas by using this program it shows 14515000. I give the coding for the reference. I need some one help on this problem

thanks.

[CODE=c] #include <stdio.h>
#include <conio.h>
main()
{
float a,b,c,d,f,g;
clrscr();
printf("Enter Amount : ");
scanf("%f",&a);
printf("Enter Period : ");
scanf("%d",&b);
printf("Enter Int : ");
scanf("%f",&c);

d=c/100;
f=a * pow((1+d),b);
printf("%.2f",f );
getch();
}[/CODE]

[CODE=c]scanf("%d",&b);

%d should be %f.

Also you should be including math.h to predeclare the pow function.

%d should be %f.

Also you should be including math.h to predeclare the pow function.

Yea, you declared all your varaibles as floats. Either do what banfa said or, to have that value as an integer, declare b as an integer.
