Programmers Area: Cricket game in C language

A simple Cricket game program in c language to show using simple concepts how cool programs can be made.In this article you will also learn how to generate random numbers. I have not used any graphics to make the source code easy to understand.

EXPLANATION

Let start with select() function

Whenever game starts first select() function is called. At first toss randomly gets value either 0 or 1, now we enter our names which are stored in variable player1 and player2 and then enter number of over’s which is stored in e. Now when you press 1 or 2 for toss than condition is checked (if(toss==0)) , nothing is related to head or tails computer randomly choose who wins the toss .Now suppose player 1 wins the toss and let he/she select batting than case 1 will execute and bat1() function is called

bat1()

Three parameters are passed to the function i.e. number of over’s, name of player 1 and ew(player 2 score).There is no need of ew in first inning but as we are using bat1() function for batting of both the players and not making any separate function for batting of second player therefore we have passed ew with initial value 1000 so that condition if(check<totalrun) always become false in first innings .

In this function number of over’s are multiplied by six, for loop will execute for that much times. Now getch() function is called it simply holds the screen until you press any key . When you press any key than score() function is called.

score()

This is the main part of our program . Now random numbers are generated between 0-7 using rand() function which are stored in run .We will discuss later how random numbers are generated .If you will see the program than you find that I have not taken case 1,case 2,etc instead I have started from case 4 ,this is because when value of run become 0,1,2,3 than same line get printed so it is only to make the program more compact.

bat1() function returns total runs which is stored in we and batting of second player starts .In batting of player 2, loop will break in three condition i.e. either over’s are finished or it gets out or it score more runs than player 1 .now when player 2’s batting is over than con() function is called .

con()

Four parameters are passed to the function i.e. player 1’s name and score and player 2’s name and score.

By comparing the scores it decides who won the game and print it on the screen.

In this way you can see other cases also.

Now let us understand how random numbers are generated in C language?

To generate random numbers in C you can use rand() function that produces a random number in the rang 0 to RAND-MAX .The RAND-MAX is defined in stdlib.h which gives you the maximum value returned by rand(). Consider the following code that generates five random numbers:

#include<stdio.h>

void main()

{

int a,i;

for(i=0;i<5;i++)

{

a=rand();

printf("%d\n",a);

}

getch();

}

OUTPUt

Re-Execute the above code you will get the same numbers ,that means random numbers are being repeated .If you want to generate different random numbers every time , use srand() function .The srand() function starts or seeds the random number generator from a point that depends on the value we pass to srand () as argument. Therefore to generate different random numbers every time, you should seed the generator with truly variable value such as system time.

Now if you change the above code as given below, you will get different random numbers every time you execute the code.

#include<stdio.h>

#include<time.h> //To obtain system time through time_t

void main()

{

int a,i;

time_t t; //t is time type variable now

clrscr();

(unsigned) time(&t); //time(&t) function will initialize time variable t with system time .

srand(t); //seeds the random number generator

for(i=0;i<5;i++)

{

a=rand();

printf("%d",a);

}

getch();

}
OUTPUT

Remember that srand() should be invoked just once prior to the loop and not every time before generating a random number through rand().In my program I have invoked srand() only once during toss and after that I have not invoked it in any function.

In my program I have use s=rand()%8+1 ; so that I can generate random numbers within range 1-8.

If you still not get the concept of random numbers than don’t worry I also found some difficulty in starting but with time all things become clear, just remember above codes.

Any questions regarding to program please write in comments.
