Basics of C programming

I wrote code for sinx

But it is showing output as INF

Why INF?? what's wrong with code ....
plz help

Code:

#include<stdio.h>

#include<math.h>

int main()

{

float x,t=0,sum;

int i,n,sig=1;

printf("Input X,N");

scanf("%f %d",&x,&n);

x*=(3.14/180);

sum=x;

for(i=0;i<n;i++)

{

sig*=-1;

t=(sig*x*x)/(2*i*(2*i+1));

sum+=t;

}

printf("SIN(X) = %f\n",sum);

return 0;

}

:snore:

Re: Basics of C programming

In you code you are using the for loop that starts from zero.

Code:

for(i=0;i<n;i++)

So when the loop runs for the first time, you get infinite in the variable t and you sum become infinite.

Code:

t=(sig*x*x)/(2*i*(2*i+1));z

Whatever you add to Infinite, the result will be infinite

Start your loop from 1 (ie for(i=1;i<n;i++)
