Maybe you want this
for (int i = 0; i < 5; i++) {
for (int j = i + 1; j < 5; j++) {
// some code here
}
}
note the j = i + 1
سؤال
I am working on a project and need a little help with the behavior of nested for loops. The following code is what I have tried to use
for (int i = 0; i < 5; i++) {
for (int j = 1; j < 5; j++) {
// some code here
}
}
I am trying to compare cards in a players hand for a poker game. I want to check if the player has two cards of the same rank. Using the above code will double count some cards and I do not want this. I did some work and figured that to compare each card with another card once, I would need to check
i=0 : j=1, j=2, j=3, j=4
i=1 : j=2, j=3, j=4
i=2 : j=3, j=4
i=3 : j=4
I am not sure how to accomplish this check with nested for loops. Right now my nested for loop is checking
i=0 : j=1, j=2, j=3, j=4
i=1 : j=1, j=2, j=3, j=4
i=2 : j=1, j=2, j=3, j=4
i=3 : j=1, j=2, j=3, j=4
I have tried to increment j after each loop but it did not give me the results I wanted. Does anyone know how I can accomplish this?
