Harmanjit

Sorry, but how will i ask that what fault i am at

Dima

Use pastebin or hastebin services

Dima

or if your code is short, post it here using Monospace style

Dima

Because it’s so hard to read your screen photo, which also is rotated

Harmanjit

I will search about pastepin or hastebin n monospace, i hv no idea , i m a beginner

Harmanjit

Wil try not to post photo

#include <stdio.h> void main() { int salary, sum=0, deduction=0, month=1, i=1; printf("Enter your salary from January (01) to December(12) to find our annual salary and deductions\n"); do { printf("Enter your salary of month %d: ",month); month++; scanf("%d",&salary); sum=sum+salary; deduction=deduction+(15000-salary); i++; } while(i<=12); printf("\nTotal salary is %d",sum); printf("\nTotal deduction is %d",deduction); return 0; }

if u return 0; from main function, it should be int main()

Explain malloc()

Sandy

I am beginner to c++ so please tell me how to learn

I_Interface

Explain malloc()

int* ptr = malloc(10 * sizeof(int)); creating array of int digits for 10 elements

I_Interface

for example

malloc returns a pointer from where it allocated a memory

to allocate a memory for dynamic array in C

Ok...but when we use it?? Any example

I_Interface

int* ptr = malloc(10 * sizeof(int)); creating array of int digits for 10 elements

lol it's not an example ???

Explain malloc()

malloc(): This function is used to allocate memory dynamically. This allocates memory during runtime. Imagine a situation where you want to calculate the sum of 'n' numbers and you declare an array for it. 'n' can be any number that user will enter. eg: int arr[100]; now when you ask the user to enter the value of n and the user enter say for eg: 20 in that case you waste (100-20) = 80 locations which is 80 * 4 bytes assuming sizeof(int) is 4 bytes wouldn't it be nice if there was some way to declare variable after user entered the value of 'n' This shortcoming is handled by malloc() eg: int n; printf("Enter n?\n"); scanf("%d",&n); int *arr = (int *) malloc(n*sizeof(int)); // memory is allocated on demand and you've have to delete after you are done with the memory.
