Pictorial Presentation:

Calculate profit and loss

Sample Solution:

C Code:

#include <stdio.h>
void main()  
    int cprice,sprice, plamt; //cprice is Cost Price and sprice is Selling Price, plamt denotes total profit/loss  

    printf("Input Cost Price: ");  
    scanf("%d", &cprice);  
    printf("Input Selling Price: ");  
    scanf("%d", &sprice);  
    if(sprice>cprice) //calculate profit  
        plamt = sprice-cprice;  
        printf("\nYou can booked your profit amount : %d\n", plamt);  
    else if(cprice>sprice) //calculate loss  
        plamt = cprice-sprice;  
        printf("\nYou got a loss of amount : %d\n", plamt);  
    else //No Profit No Loss  
        printf("\nYou are running in no profit no loss condition.\n");  

Sample Output:

Input Cost Price: 500                                                                                         
Input Selling Price: 700                                                                                      
You can booked your profit amount : 200

C Programming: Tips of the Day

Why do C and C++ compilers allow array lengths in function signatures when they're never enforced?

It is a quirk of the syntax for passing arrays to functions.

Actually it is not possible to pass an array in C. If you write syntax that looks like it should pass the array, what actually happens is that a pointer to the first element of the array is passed instead.

Since the pointer does not include any length information, the contents of your [] in the function formal parameter list are actually ignored.
