What appropriate input function for string should i use to store value into an empty array? And how? 😬

English isn't a basis of intelligence I guess, besides it's just a typo error.
Hear hear! I used to teach English when I was at university in London, to foreign students learning English in London. It was easier to assume the person was clever than me and if I listened and tried to understand them I would learn more. Having just one spoken human language limits your thinking and thoughts🤓

Like scanf("%s",szArray);
Vlad
Consider using fgets or gets_s for the string input
Vlad
scanf("%s", string) isn't safe

Glad that canary exists. Jumping to malicious code after return ain't fun

Are there any high speed and lightweight c++ libraries for logging?

If its an int array use a for loop

#include <iostream>
using std::cout;
using std::cin;
int main()
{
int UserNumber;
char Grade;
cout << "Enter your grade scored in the Programming class: ";
cin >> UserNumber;
cout << "\n\n\n";
if (UserNumber > 90 && UserNumber < 101)
{
Grade = 'A';

Thanks 🙁

Try to use ` ``
for code, before and after, so it looks like
myClass{
int val = 0;
};
Also for long things try to use https://gist.github.com/
Diego
Can someone help me to arrange the code, like if I'm going to input a number exceeded to 100 its output will be undefined value.
If it exceeds 100 it's gonna fail all the ifs and fall into Grade = 'Z'
Diego
If you wish to validate then add an extra if that checks if it's less than 101, if so, output that it's invalid
🇵🇭🇷🇺
But it keeps on appearing that 89-100 is undefined

Paste the code in the big text box, add a description or a filename optionally
Diego
Then just click create and it'll give you a link

Hey everyone, ¿how are you? I need some help on one particular issue.
I'm very new on programming, not even a year on this. So please bear with me. I'll try to explain the best way I can my issue.
V
Its kinda long explanation, so I asked for permission to admin Dima and said its okay.

```#include <stdio.h>
#include <string.h>
int main(){
const int SIZE = 100;
char letter [SIZE];
int num,i;
int num2;
scanf("%d", &num);
for(i=0; i<num; i++){
scanf("%c", &letter[i]);
}
scanf("%d", &num2);
int index=num2;
printf("%c", letter[index]);
return 0;
}```

Why does the loop count twice?
Diego
But it keeps on appearing that 89-100 is undefined
https://gist.github.com/DiegoG1019/b4d4bb16bd06c53bf31f7131d5c07653
Diego
Try this out
I put your get grade code into a function, and UserNumber is now an argument
I use a foor loop that stops when i > 150 and each loop adds 5 to i
Should be much easier to see where the mistake is
Diego
It seems to be every time there's a 10th number; maybe the problem is using > and < rather than >= and <=
Try out changing those where you see it relevant

Hey guys! I'm new to c++ ,while I'm reading the book c++ primer, I try to do some experiment with the problem 12.24, but there's something out of my expect and made me confused, here is my code
#include <iostream>
int main(int argc, char* argv[])
{
char * a = new char[10];
std::cin >> a;
std::cout << a << std::endl;
delete [] a;
return 0;
}
Terror
after compiling it I tried to enter some string longer than 10 but still got the full string
Terror
Is there something wrong with my code or just compiler's magic?
.
Hi can you help me in the exams c++?

Why does the loop count twice?
%c does not skip white-space before converting a character
scanf(" %c", &letter[i]);
Try adding a space before %c in scanf like above

Is there a centralised place to find 3rd party libs to do whatever you want
