Write a program in C that allows the user to enter two integers. When the first integer is bigger than the second, the program should call a function to subtract these integers. When the second integer is bigger than the first, the program should call a function to multiply them. When first integer is equal to the second integer, the program should call a function to add these integers. When one of the integers is a zero, the program should insert these two integers into an array of size 2. Then the program should call a function and pass these two elements of an array as actual parameters to a function that will add these two elements. Otherwise, the program should output: invalid input.

not able to take input need help

What does it say?

no

Help me

Thanks but problem solved☺️

no

Why ?

If you wrote some code which is not working show that

Why ?

Why ?

Depends what you want to extract, maybe try regex, or split it based on the comma

First row has 5 value 5,10,20,15,20 i have to store them like integer. And other rows have service no, service, number of services, service price. Can you help me?

read row by row, find a function on the internet that split a row into an array based on a delimiter then convert each piece to integer.

Anyone please help to find next permutations with c language

That's so easy, are you in highschool or something

Don't be a pretentious douche

What is the best way to learn C ? Reading or Videos ... Any resources ?

Lol

i don't think there are any permutations of C language. you can definitely write one with one-to-one correspondence between its keywords and C's keywords. then write a script to find and replace the keywords and call it a compiler.

Bro i have a array of string.and i want to find next permutation of that string array

nobody is going to help you with stupid shit that you can google. post your code and people might help with what is wrong in it.

I mean, you can't be in college without knowing something like that

👍

goo.gl/search?how+to+permutation+c

not for next permutaiona

Am I missing something? Looks like a couple of conditions

goo.gl/search?next+permutation

https://en.cppreference.com/w/cpp/algorithm/next_permutation I looked up possible impl Doesn't seem so obvious to me

Oh, we're not talking about the same program, sorry

it was about this

Guys how many years does it take to master C++?

Instead of forwarding you can use links for messages

the leetcode one even has complexity analysis done for you

He was quoting to remind us which program I was talking about

Hi

I wanna write eeprom string values like; 10,20,30 30,2,8 So i wrote; WriteStringtoEEPROM(0, "10,20,30"); WriteStringToEEPROM(?,"30,2,8"); What do I have to write inside of "?"?
