Question

Write a program that finds either the largest or smallest of the ten numbers as command-line arguments. With –l for largest and –s for smallest number, if the user enters an invalid option, the program should display an error message.
Example runs of the program:
./find_largest_smallest –l 5 2 92 424 53 42 8 12 23 41
output: The largest number is 424
./find_largest_smallest –s 5 2 92 424 53 42 8 12 23 41
output: The smallest number is 2

1) Use atoi function in <stdlib.h> to convert a string to integer form.

2) Generate the executable as find_largest_smallest

Explanation / Answer

#include //Always use meaningful names for types typedef unsigned char boolean; #define True 't' #define FALSE (!True) //this is a really neat trick for swapping values efficiently void swap(long* a,long *b) { *a=*a^*b;*b=*b^*a;*a=*a^*b; } //Here's a readability improvement #define until(condition) while(!(condition)) int main(int n, char*args[]){ double *d; int i; char input[5]; //should be long enough for most doubles. boolean sorted = FALSE; //In C, you need to specify the array size beforehand, so ask printf("Please enter the length of the array "); gets(input); //scan the input string and convert to a value sscanf(input,"%s",&input[0]); n=(long)atol(input); //allocate space, make sure you get the order of arguments right. d = calloc(sizeof(double),n); //Get and sort the array until (sorted) { for (i=0;i
