What is wrong with my code? There is an error at {. Its after else.

First of all, to make code easier to read for people who want to help you, please use code tags. The little http://www.cplusplus.com/ico/text_code.png icon under format next to your text box when you are creating your thread will do that.

The solution to your problem is to use else if (coin==0)

The else statement will only execute the the next block of code if the if statements that it is attached to evaluates to false. You need to say: if my if statement is true do this, else check and see if this is true.

Can you please teach me how to include srand????

[giblit]

srand( (unsigned) time(NULL) );

You should call srand only once to get the seed at the beginning of your program and then call rand() when ever you want a random number. You will want to use the modulus operator though.

yeah you only need to call srand once because it sets a global variable (i think called seed) that rand uses to return a random int. i would recommend <random> or whatever the new c++11 one is

On a side note a pseudo random number generator (PRNG) are really just sequences of numbers. The formula for them I believe is something like
a₀ = seed
a_n = (a_n-1 * r + b) % m
Where n is the number of sequences , r is a rate you choose , b is a number to increase and m is the number you are taking the modulus of ( max value )
