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().
