Just tell me what should I do in main function and in user defined function. I am totally confused.

Write a C++ Program that contains four user defined function(s): addition(), subtraction(), division(), multiplication(). Develop a calculator as follows: • In main() function: o A menu with choices addition, subtraction, division and multiplication must be displayed. o Get two numbers and a choice from user o Call the respective functions with user given number as parameter using switch statement o Print the result from addition (), subtraction (), division (), multiplication (). • In user defined functions: o Plus and minus function get two integer values and return integer. o Multiply and Divide functions get two integer values and return double.

#include<stdio.h> int sum(int num1,int num2); int mul(int num1,int num2); int div(int num1,int num2); int sub(int num1,int num2); int main() { float num1,num2; char op; printf("Enter First Number:"); scanf("%f",&num1); printf("Enter your operation:"); scanf(" %c",&op); printf("Enter Second Number:"); scanf("%f",&num2); if(op=='+') { sum(num1,num2); } else if(op=='*') { mul(num1,num2); } else if(op=='-') { sub(num1,num2); } else if(op=='/') { div(num1,num2); } return 0; } int sum(int num1,int num2) { printf("Sum is %d",num1+num2); return num1+num2; } int mul(int num1,int num2) { printf("product is %d",num1*num2); return num1*num2; } int sub(int num1,int num2) { printf("Subtraction is %d",num1-num2); return num1-num2; } int div(int num1,int num2) { printf("division is %d",num1/num2); return num1/num2; }

#include<stdio.h> int sum(int num1,int num2); int mul(int num1,int num2); int div(int num1,int num2); int sub(int num1,int num2); int main() { float num1,num2; char op; printf("Enter First Number:"); scanf("%f",&num1); printf("Enter your operation:"); scanf(" %c",&op); printf("Enter Second Number:"); scanf("%f",&num2); if(op=='+') { sum(num1,num2); } else if(op=='*') { mul(num1,num2); } else if(op=='-') { sub(num1,num2); } else if(op=='/') { div(num1,num2); } return 0; } int sum(int num1,int num2) { printf("Sum is %d",num1+num2); return num1+num2; } int mul(int num1,int num2) { printf("product is %d",num1*num2); return num1*num2; } int sub(int num1,int num2) { printf("Subtraction is %d",num1-num2); return num1-num2; } int div(int num1,int num2) { printf("division is %d",num1/num2); return num1/num2; }

I have not allowed to use any other dictionary, but iostream.

ooh sorry

Are you both kidding me?

I just want to say the header. We have never studied about studio.h . We are allowed to use <iostream> only.

brother logic is same just syntax is different

How do I start learning c program

Hi how can i take a number from my user and then first calculate average of odd numbers then calculate average of even numbers like this e.g 2569 is the input (9+5)/2 = 7 for odd numbers (2 + 4) /2 = 4 for even numbers

I've given half logic find the divisor by yourself!

can't you help me to write the exact code of that🤦‍♂? I'm beginner & i want to learn

Do write the code by yourself

For(int I = 1; I <= numberLength; I++){ If(I % 2 == 0){ SumOfEvenDigits += n%10; } Else{ SumOfOddDigits += n%10; } n/=10; }

hey everyone, i have a task to write a function that will get 2 arrays and their size: int contain(int big[], int size_b, int small[], int size_s) the program should check if the small array is a sub array of the big array, if true should return the Index number of the first number in the small array, else return -1. Example: 2 4 61 5 8 5 56 89 3 -2 5 56 89 3 -2 function should return 5. 9 5 12 7 8 -2 4 32 900 13 9 5 12 8 7 function should return -1. can someone help me please?

Does anyone of you have any familiarity with xlib.h?

nohello.com also there should be Xlib channel on freenode

that is a russian website

I don't want to get banned like in every other group, but I can't stand the idea of not telling you how that website's content is unrelated to my request. Moreover if I can't ask questions about xlib here (considering it's not something so uncommon... it's a c library), than I don't know where to ask it. Now if you whish you can ban me, I'm not here 'cause I want to ask how to write a loop to pass my c++ test at school, I'm really sorry for that

Sorry, about that. This site is related to metaquestions. You can ask questions about Xlib here, moreover i think you even can ask metaquestions. But if you want your questions answered you would mind asking them. I actually believe that your question about Xlib would be answered on corresponding channel. #Xlib on freenode. Just think about how where more people know something about Xlib on this chat or on channel which name is Xlib. I don't want to ban you neither i can. If you wan't to get banned better ask Danya, i don't have any moderator rights here

Hello everyone! Please, give an advice: I want to use func ptr to some functions that have various signature. What is the best way? Templates or smth like this, idk. I'm looking at smth like this for c++11 int (*my_f)(int, int, int, <smth>) = 0; If (cond1){ my_f = my_inh1; } else if(cond2){ my_f = my_inh2; } Inherited: int (*my_inh1)(int, int, int, uint8_t) int (*my_inh2)(int, int, int, uint16_t)

I don't think thee is a good way to do this.. At the point you call my_f, how do you differentiate what the last parameter should be?

Hello everyone

I thought that maybe there are hacks like union or templates for this case. But I'm not so good in c++. That's why and asking:))

I mean sure, there are "hacky" ways, but you should think about "why" you would do this and how you would differentiate on call site. A function pointer is like an interface, the parameters are well defined so you can use them without thinking about the actual implementation. If you need to pass different typed parameters based on a condition, call the functions directly?

what do you mean by a hacky way ?

I can call directly, but i want to set methods, that i shall use in the beginning of my own method cause i want to reduce the same conditions

using func_type_1 = void(*)(int); using func_type_2 = void(*)(double); std::variant<func_type_1, func_type_2> the_func; if (condition) { the_func = first_func; } else { the_func = second_func; } std::visit( std::overloaded { [](func_type_1 arg) { std::cout << arg(10) << std::endl; } [](func_type_2 arg) { std::cout << arg(42.0) << std::endl; } } ,the_func);

and should i give external link? or just screen?
