Basic string formatting in C#

Shanxx — Sun, 26 Nov 2023 03:35:03 +0000

Character Escape Sequence

An escape character sequence is an instruction to the runtime to insert a special character that will affect the output of your string. In C#, the escape character sequence begins with a backslash \ followed by the character you're escaping.

\ - use case -> Console.WriteLine("Hello \"World\"!"); -> Hello "World"!
-> backslash \ followed by the character you're escaping
\n - new line
\t - new tab big space

Verbatim string literal

will keep all whitespace and characters without the need to escape the backslash.

Console.WriteLine(@"    c:\source\repos    
        (this is where your code goes)");

Output
c:\source\repos    
        (this is where your code goes)

Unicode escape characters

add encoded characters in literal strings using the \u escape sequence, then a four-character code representing some character in Unicode (UTF-16).

Console.WriteLine("\u3053\u3093\u306B\u3061\u306F World!");
Output -> // Kon'nichiwa World

String Interpolation

int version = 11;
string updateText = "Update to Windows";
Console.WriteLine($"{updateText} {version}!");

Outpt:
Update to Windows 11!

CS50x : Practice Problems (Debug)

Problem link

Given Code

This is a code with bug that you will solve

// Become familiar wih C syntax
// Learn to debug buggy code

#include <cs50.h>

int main(void)
{
    // Ask for your name and where live
    name = get_string("What is your name? ")
    location = get_string("Where do you live? ")

    // Say hello
    print("Hello, %i, from %i!", name, location)
}

Bug 1

You'll see that it will give you this error when running/typing make debug

debug.c:9:5: error: use of undeclared identifier 'name'
    name = get_string("What is your name? ")
    ^
1 error generated.
make: *** [<builtin>: debug] Error 1

to solve this we need to add what type is the name is it string? yes!!
see this
change the code like this

    string name = get_string("What is your name? ");
    string location = get_string("Where do you live? ");

and also always don't forget the semi colon in the last line or else you will get this error

debug.c:9:52: error: expected ';' at end of declaration
    string name = get_string("What is your name? ")
                                                   ^
                                                   ;
1 error generated.

Bug 2

debug.c:13:5: error: implicit declaration of function 'print' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
    print("Hello, %i, from %i!", name, location)
    ^

This codes means there's no print syntax on c language.
To solve this we need to change print to printf
and also don't forget to add #include <stdio.h> in the top above/below the #include <cs50.h> or else the printf will not work

Bug 3

Now for the last bug!!

debug.c:13:35: error: format specifies type 'int' but the argument has type 'string' (aka 'char *') [-Werror,-Wformat]
    printf("Hello, %i, from %i!", name, location)
                   ~~             ^~~~
                   %s

as the error say we cant put i in there because the name is a string not an number we can only add %i if the variable is a number

so to fix this change the 2 %i into %s because they are both strings and also add semi colon in the last part
like this

printf("Hello, %s, from %s!", name, location);

Solution

// Become familiar wih C syntax
// Learn to debug buggy code
#include <stdio.h>
#include <cs50.h>



int main(void)
{
    // Ask for your name and where live
    string name = get_string("What is your name? ");
    string location = get_string("Where do you live? ");

    // Say hello
    printf("Hello, %s, from %s!", name, location);
}

yosh!!!

Shanxx — Wed, 07 Sep 2022 01:45:56 +0000

Math.max()
will get the highest number in the array
Math.min()
will get the lowest number in the array

...arr will copy all the content of the array passed

function sumAllBetween(arr){
    let highNum = Math.max(...arr)
    let lowNum = Math.min(...arr)
    let arrayBetween = []

    for(let i = lowNum; i <= highNum; i++){
arrayBetween.push(i)
    }
    return arrayBetween

}

console.log([9, 1])
