Because all the time it always greater than a .u have to put one extra condition with
like as below .Just think in this direction.
e>a && e<b && e<c
like as below .Just think in this direction.
e>a && e<b && e<c
what is ur expectation i mean suppose u have entered a as monitor and amount 1250 then if amount is greater than and less than b and less than then should it do num1=e-a;
std::cout<<"Your change is:\n"<<num1;
then condition should be like
if (e>a && e<b && e<c)
{
num1=e-a;
std::cout<<"Your change is:\n"<<num1;
}
std::cout<<"Your change is:\n"<<num1;
then condition should be like
if (e>a && e<b && e<c)
{
num1=e-a;
std::cout<<"Your change is:\n"<<num1;
}
how about the monitor b and c ??? for example i choose monitor b and entered 2000 as the amount of my money how can i have the change as 700 ??
