C Exercises: Produce the following table of values
C Basic Declarations and Expressions: Exercise-79 with Solution
Write a C program using looping to produce the following table of values:
x x+2 x+4 x+6 -------------------------------- 1 3 5 7 4 6 8 10 7 9 11 13 10 12 14 16 13 15 17 19
Sample Solution:
C Code:
#include<stdio.h>
int main()
{
int x;
printf("x\tx+2\tx+4\tx+6\n\n");
printf("---------------------------\n");
for(x=1; x<=15; x+=3)
printf("%d\t%d\t%d\t%d\n", x, (x+2), (x+4), (x+6));
return 0;
}
Sample Output:
x x+2 x+4 x+6 --------------------------- 1 3 5 7 4 6 8 10 7 9 11 13 10 12 14 16 13 15 17 19

C Programming: Tips of the Day
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().
