why it does not enter the if statement?

I have a code made to check an if statement and then perform something. here is the if statement

for(int j=0;j<10;j++)
{
 if(removed_Num==USERS[j])
 { //do something}
}

USERS[j] is a 13 element array and removed_Num is also a 13 element array. I've check in the debug mode and saw USERS[j] is equal with removed_Num. but it doesn't enter the if statement. why is that?

    Clive1 is right.

    If you compare two array with all indexes, you need select index one by one and compare them.

    ​

    I wrote a example,

    1. Int Issamearray;
    2. for(int j=0;j<10;j++)
    3. {
    4. Issamearray = false;
    5. if(removed_Num[j] ==USERS[j])
    6. { Issamearray = True;}
    7. }
    8. If (Issamearray == True)
    9. {
    10. //do something}
    11. } ​

    ​Not; if you make this with while not for, it can will work faster.

    I hope you understand clearly.

    As described that isn't how C works.

    The comparison here is of the address of an array vs the element in a second array. You basically ask it to compare apples and oranges, which usually they don't.​
