Calculate the sum of the following series. 1 - x^3/3! + x^5/5! .. upto 10 terms.

#include <stdio.h>

int main(void)
{
int x, cnt = 1, val;
float sum = 1.0, numr, denr;

printf("\nEnter the value of x : ");
scanf("%d", &x);

for(cnt = 1 ; cnt <= 2 ; cnt++)
{
numr = denr = 1.0;
for(val = 1 ; val <= (2 * cnt + 1) ; val++)
{
numr = numr * x;
denr = denr * val;
}
if(cnt % 2 == 0)
sum = sum + (numr / denr);
else
sum = sum - (numr / denr);
}

printf("\nThe sum is %f", sum);


return 0;
}
