How do you write a program that generates three random numbers and prints the largest?

For this you need two variables, a and b. Generate the first number and assign it to a. Generate the second and assign it to b. If b is greater than a, assign b to a. Generate the third number and assign it to b. If b is greater than a, assign b to a. Print a.
A better method is to use the following function to determine the largest of any two values:
int max (int x, int y) { return x>y ? x : y; }
Once you know the largest of any two values you can easily determine the largest of any three values with a nested call:
int max_of_three (int a, int b, int c) { return max (max (a, b), c)); }
Note that we determine the largest of a and b first and then pass that value to a second call along with c, thus establishing the largest of all three.
To determine the largest of n values, store the numbers in an array and pass the array and its length to this function:
int max_of_n (int a[], size_t n) {
int m = a[0]; // store first value
while (--n) if (a[n]>m) m=a[n]; // update m whenever a[n] is greater
return m;
}

How do you write a c program to generate first n natural numbers using a for loop?
#include<stdio.h> main(void) { int n; int i; printf("Type n: "); scanf("%d",&n); for(i=1;i<=n;i++) //generates natural numbers from 1,....,n. printf("%d\n",i); //prints these numbers to standard output }
How do you write a program which reads a list of ten numbers and print the list in reserve order in c program?
The simplest way is probably to read the numbers into an array and then prints each element of the array starting at the last one and moving backwards.
