C Exercises: Generate a random number
C Variable Type : Exercise-5 with Solution
Write a C program to generate a random number.
Sample Solution:
C Code:
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
int main ()
{
int number, input;
/* initialize random seed: */
srand ( time(NULL) );
/* Generate a random number: */
number = rand() % 10 + 1;
do {
printf ("\nGuess the number (1 to 10): ");
scanf ("%d",&input);
if (number > input)
printf ("The number is higher\n");
} while (number!=input);
printf ("That is correct!\n\n");
return 0;
}
Sample Output:
Guess the number (1 to 10): 6 The number is higher

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().
