Another easy one. No need to take any input. Given a formula, you have to only print output.


Source code:

#include<stdio.h>

double F[10];

double Res[10];

void getFact() {

	int i;
	F[0] = 1;

	for( i = 1; i<10; i++) {

		F[i] = i*F[i-1];

	}
}

void getRes() {
	int i;

	double sum = 1;
	Res[0] = 1;

	for(i = 1; i<10; i++) {

		sum += F[i];
		Res[i] = (1/F[i]) + Res[i-1];

		if(i > 2) printf("%d %.9lf\n",i,Res[i]);

	}
	
}

int main() {
	getFact();

	printf("n e\n");
	printf("- -----------\n");
	puts("0 1");

	puts("1 2");
	puts("2 2.5");
	getRes();

	return 0;
}
