So I’m trying to add an element to the beginning of a list. The function prepend_list is at line 27. I’m trying to make it in two different ways, one returns a list back and one is a void function. #include "base.h" #include "string.h" typedef struct Node Node; struct Node{ int value; Node* next; };… Read More I don't understand fully how lists in c work

// here is my code to find a factorial of a number: int get_factorial(int num) { auto sum = 1; while(num > 0) { sum = sum * num; num–; } return sum; } // this works to give me the factorial but my assignment wants me to return a string. so if my parameter… Read More Display a factorial sequence as a string

Given the struct ListNode: typedef struct _listnode { int item; struct _listnode *next; } ListNode; how to recursively reverse a linked list using a function with void return type and single parameter for passing in the address pointing the head ListNode of the linked list? (note that the function should not have a return type;… Read More Recursively reverse a linked list in C

I have the code below which should convert an user message input to its bits counterpart. For example "Hi!" should be converted to 01001000 01001001 00100001 #include <stdio.h> #include <stdlib.h> #include <cs50.h> #include <ctype.h> #include <string.h> int printbulbs(int ascii_input); int main(void) { char *Mesaj = get_string("Message: "); int size = strlen(Mesaj); int *ascii_conversion = malloc(size… Read More Trying to convert a message in its bits counterparts

This program is supposed to return the highest number in the array "array". But it only returns the highest number between the first and second numbers. Why? #include <stdio.h> #include <stdlib.h> int HighestNumber(int* array) { int highest = INT_MIN; for(size_t x = 0; x < sizeof(array) / sizeof(array[0]); x++) if(array[x] > highest) highest = array[x];… Read More Program does not find highest number in array as intended

I’ve seen a similar post on StackOverflow about this error code, but theirs seemed to have an error code line, and they were also attempting something slightly different in their function. I’m trying to count the number of a specified character in a string (inputting p and apple would return 2, for example). At some… Read More error: lvalue required as increment operand without an error line

I have a little problem which occurs after trying to execute function delete_all(). Any idea why Visual Studio is throwing me an error: Invalid address specified to RtlValidateHeap, instruction __debugbreak() or something similar Everything works perfect until I want to execute this function. #include <iostream> using namespace std; struct node { string name = "n1";… Read More Can't delete node from node list

Firstly I’m using C language. I want a variable that I refer to as a parameter to change outside the function when it is changed inside the function. But the problem is that the variable is of type linked list and I want to add to the linked list. So what I’m trying to do… Read More Changing the variable assigned as a pointer to the parameter in C

//Prime function #include <stdio.h> #include <math.h> char Premier(int N){ int i; char notpremier="Nombre n’est pas premier"; //Number is prime char premier="Nombre est premier"; //Number isn’t prime for(i=2;i<=sqrt(N);i++){ if(N % i==0){ return notpremier; } else{ return premier; } } } int main() { printf("%c",Premier(10)); return 0; } However, when I choose to return an int data… Read More Why is this function not returning a char data type?

What option is recommended in C to return an array from a function? Option 1: void function_a(int *return_array){ return_array[0] = 1; return_array[1] = 0; } Option 2: int* function_b(){ int return_array[2]; return_array[0] = 1; return_array[1] = 0; return return_array; } >Solution : This function int* function_b(){ int return_array[2]; return_array[0] = 1; return_array[1] = 0; return… Read More C Return Value from Function Best Practice
