Thanks for your input. The following is the working scripts

    #include <stdio.h><br />
int main (void)<br />
{<br />
int x;<br />
float sum=0;<br />
double PI;<br />
<br />
printf("Please enter the terms of series that should be included> ");<br />
scanf("%d", &#038;x);<br />
<br />
for (int i=1; i<x; i+=2)<br />
if (i%4==1)<br />
sum=sum+1./(double)i;<br />
else<br />
sum=sum-1./(double)i;<br />
<br />
PI= 4*sum;<br />
printf("The sum is %fn", sum);<br />
printf("Approximate value of PI is %fn", PI);<br />
<br />
return 0;<br />
}

#include <stdio.h>

int main (void)

{

int x;

float sum=0;

double PI;

printf("Please enter the terms of series that should be included> ");

scanf("%d", &x);

for (int i=1; i<x; i+=2)

if (i%4==1)

sum=sum+1./(double)i;

else

sum=sum-1./(double)i;

PI= 4*sum;

printf("The sum is %fn", sum);

printf("Approximate value of PI is %fn", PI);

return 0;
