Hi, here is the thing, I'm trying to make my university grading table on C++, when i fill in the grades it should tell me what i have accumulate.
the thing is that when i insert the text grades it shows a zero when i click the buttom.
the math is simple `[ j ]` are the int and the `[ i ]` are the decimals they must add up and multiply by the percent which in this case is Edit5,E6,E7,E8 here is the code; acu= the acumulated `[ j+(i/10)]` i being the decimal.

it keeps printing zeros
and the 100 101 .... are special things which are all the conditions `if(d==73 || d==74)`

here something extra, every time a divide i/10 it gives me zeros, and i see the zero comes when dividing things example : tot1=(acu*(h/100)); and everything multiply by zero is zero so we get zeros on the label.
how can i make the division to give the right number?

If i=1, then i/10 will be zero because its truncated. Use a double

I change everything to double : double i,j,... I don't get more zeros but it won't take the decimals like i/10 = 0.1 how can i get the decimals?

Example? Not sure what you're saying.

i solved the problem, when ever i did a division like 1/10 it gave me a zero, in order to get 0.1 from the division above, i use instead 1*0.1 which is the same thing and it solved the problem with the decimal now the label is showing the decimals too for the interger thanks anyway...
