You can generate a random number in C using the following code: int myRandomNumber; srand(time(NULL)); // seed the random number generator myRandomNumber = rand(); // each time you call this function there will be a different random number. Generate a random number, and output it. Use if statements to determine if the number is odd or even, and output a message to that effect. Similarly, output if the number is divisible by 3, and if it is divisible by 10. Use the % operator to achieve this. Run the program, and print the results several times using different numbers to be sure that it’s working. Hint: In C you can not declare variables after you write executable code. For example if you call the srand function, and then declare some more variables after that call, the program will not compile. The compiler messages are not very helpful. Put all the variable declarations at the top of the function.
Solution
#include <stdio.h>
#include <stdlib.h>
int main()
{
int myRandomNumber;
srand(time(NULL));
// seed the random number generator
myRandomNumber = rand();
if(myRandomNumber % 2 == 0){
printf(\"Random number %d is even number\ \",myRandomNumber);
}
else{
printf(\"Random number %d is odd number\ \",myRandomNumber);
}
if(myRandomNumber % 3 == 0){
printf(\"Random number %d is divisible by 3\ \",myRandomNumber);
}
else{
printf(\"Random number %d is not divisible by 3\ \",myRandomNumber);
}
if(myRandomNumber % 10 == 0){
printf(\"Random number %d is divisible by 10\ \",myRandomNumber);
}
else{
printf(\"Random number %d is not divisible by 10\ \",myRandomNumber);
}
return 0;
}
