C Basic Declarations and Expressions: Exercise-56 with Solution

Write a C program to shift given data by two bits to the left.

Sample Solution:

C Code:

#include<stdio.h>
int main()
{
int a, b;
printf("Read the integer from keyboard-");
scanf("%d",&a);
printf("\nInteger value = %d ",a);
a<<=2;
b=a;
printf("\nThe left shifted data is = %d ",b);
return 0;
}

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().
