Hello my friends
I want to create a program in C language in the Code Block to do the bottom line:
Starting from number one, then we enter natural numbers in order. When we arrive at multiples of 5, we must enter H, if you enter a number or another, print a message.

Sorry for my bad writing. Very Happy

so something like
Code:
1
2
3
4
H
6
7
8
9
H
11
12
13
14
15
<error you must enter H for multiples of 5!
H
17
<error expected 16!


?? sometimes examples of expected behavior is better than trying to explain the behavior, especially if you have to translate it from one language to another.

Then the basic scenario would probably be using scanf or gets to read the input as a string. You'd then have a variable holding the expected number (starting at 1), and check if that variable is a multiple of five (the mod/remainder operator % will be helpful there)
  • if it's a multiple of five, you'd check if the input was "H\n" (depending on how strict you wanted to be you could compare the first character to 'h' or 'H', use stricmp/strcasecmp, or strcmp). If it does not match, then you'd print an error
  • If it's not a multiple of five then you'd try to convert the input to a number, either with sscanf or atoi (stands for ASCII To Integer), if the conversion fails or the number is not equal to the expected number then you'd print an error
In any scenario that successfully matched the expected input you'd add 1 to the variable storing the expected value. Finally you'd have all of that inside a loop so that it reads the user's input again.


so something like

Code:
char input[]
int expected = 1
while true do
  scanf("%s", input)
  if expected mod 5 is 0 then
    if input is not 'h' then print("FAIL!") else expected++ end
  else
    int result = atoi(input)
    if result is not expected then print("FAIL!") else expected++
end

This really seems like a homework assignment OP should at least attempt before asking for an answer.

Post what code you have so far and others may help fix and/or improve it.
