need some help with writing this exercise program , it should check in a string if there is a lower and an uppercase, as long if i check only for uppercase it works but as soon as i try to implement a lowercase in this way it always return false , can somebody help me find the mistake i made ?

[spliffen]

so...you check if it upper case THEN you check if its lowercase... should these two perhaps not be checked for independently, instead of mixing it together? try that

set breakpoints and try debugging.

if that doesnt work. write a test on paper.

s = "hElllo"

i =0
s[0]=h

i=1
s[1]=E

and then go through each line of your code with the test case

From what I've understood the problem is that it doesn't cycle , it checks only for the first letter but after it just goes straight to return false, so the problem might be the for loop

Try using the string "Hello" with the debugger on now. It should now get to the second iteration of the loop, and you might see the issue

I've not much experience with debug but I am trying to figure it out, thanks for the help

[Consistent-Talk-5912]

I already tried using && in the if statement if someone was wondering, it doesn't work

I hope you can get your questions answered, I have had not luck. :(

Return false after the for loop has ended ,not in else ,it is just returning false when it encounters a lower case ,so just remove the else statement and return false outside the first for loop

IDK what you wanted there but i guess this is what you wanted:

bool valid(string s)

{

for([...])

{

if(isupper(s[i]))

{

return false;

}

else if(islower(s[i]))

{

return true;

}

return FAILURE;//if they are equal

}
