C Exercises: Calculate the sum of three numbers getting input in one line
C Input Output statement: Exercise-8 with Solution
Write a program in C to calculate the sum of three numbers with getting input in one line separated by a comma.
Pictorial Presentation:
Sample Solution:
C Code:
#include <stdio.h>
int num1,num2,num3; /* declaration of three variables */
int sum;
char line_text[50]; /* line of input from keyboard */
int main()
{
printf("Input three numbers separated by comma : ");
fgets(line_text, sizeof(line_text), stdin);
sscanf(line_text, "%d, %d, %d", &num1, &num2, &num3);
sum = num1+num2+num3;
printf("The sum of three numbers : %d\n", sum);
return(0);
}
Sample Output:
Input three numbers seperated by comma : 5,10,15 The sum of three numbers : 30

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().
