#define ACCURACY 0.0001
int main() {
int n, count;
float x, term, sum;
printf("\nEnter value of x :");
scanf("%f", &x);
n = term = sum = count = 1;
while (n <= 100) {

**Output :**

```
Enter value of x:0

Enter value of x:0.1
Terms = 5 Sum = 1.105171
Enter value of x:0.5
Terms = 7 Sum = 1.648720
Enter value of x:0.75
Terms = 8 Sum = 2.116997
Enter value of x:0.99
Terms = 9 Sum = 2.691232
Enter value of x:1
Terms = 9 Sum = 2.718279
