Question

Write a C function "RandomNumber" which returns a random number in the range 0 to 51.

Answer 1

#include<stdio.h>
#include<stdlib.h>

int RandomNumber();

int main()
{
int num;
num=RandomNumber();
printf("Random number is %d",num);
printf("\n\n");
system("pause");
return 0;
}

int RandomNumber()
{
int num;
num=rand()%51+0;
return num;
}

Answer 2

You can use the rand() function from the stdlib.h library to generate random numbers in C. However, since rand() generates numbers in the range of 0 to RAND_MAX, which may not be exactly 51, you need to perform some adjustments to get the random number within the range of 0 to 51.

Here's a C function RandomNumber() that returns a random number in the range 0 to 51:

cCopy code#include <stdio.h>#include <stdlib.h>#include <time.h>int RandomNumber() {    // Seed the random number generator using the current time
    srand(time(NULL));    
    // Generate a random number in the range 0 to RAND_MAX
    int randomNumber = rand();    
    // Scale the random number to the range 0 to 51
    int scaledNumber = randomNumber % 52;    
    return scaledNumber;
}int main() {    // Test the RandomNumber function
    int randomNum = RandomNumber();    printf("Random number: %d\n", randomNum);    
    return 0;
}

In this implementation, we seed the random number generator using the current time to ensure that we get different random numbers each time the program runs. Then, we use the % operator to calculate the remainder of dividing randomNumber by 52, which ensures the result is in the range of 0 to 51. The function returns the scaled random number.
