Default QBASIC help?
I'm stuck. I need to print the total for numbers in the range of 1-100 using the FOR/NEXT loop command. Any ideas?

I just made a program to print a list of ten random numbers in the range of 1-100. The new program does not need random numbers but simply the sum of all numbers between 1 and 100.

Quote:
CLS
LIMIT = 100
FOR Index = 1 TO 100
LET X = INT(RND * LIMIT + 1)
PRINT X
NEXT Index
LET TOTAL =
PRINT TOTAL X

I don't know Qbasic, but heres the C code (should be similar for something this trivial)

Code:
int x=0, i;
for(i=1; i<=100; i++)
x+=i;

printf("%d\n", x);

You're not that far off. Before the loop, initialize a variable to 0:
Code:
LET TOTAL = 0
Then inside your loop, add the INDEX to the TOTAL.
Code:
LET TOTAL = TOTAL + INDEX

Thanks man, that helps. Complete brain fart so I just walked away from it.
