C Basic Declarations and Expressions: Exercise-45 with Solution

Write a C program to calculate the value of S where S = 1 + 1/2 + 1/3 + … + 1/50.

Sample Solution:

C Code:

#include <stdio.h>
int main() {
	float S = 0;
	int i;
	for(i=1; i<=50; i++)
	{
		S += (float)1/i;
    }
    printf("Value of S: %.2f\n", S);

	return 0;
}

Sample Output:

Value of S: 4.50

Static variable inside of a function in C

The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().

The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.

The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
