In this tutorial, we will discuss a concept of C program: find greatest of three numbers using the function
In this post, we will learn how to find the greatest number of three numbers using a user-defined function in the C programming language
In my previous post, I have explained the various approaches to find the largest number of among three numbers in C language
However, in this program, we embed the logic of the “find the greatest of three number” program in the function.
Here, I have explained how to find the greatest number from the given three numbers and how to embed this logic in the function.
Program 1
This program allows the user to enter three numbers and compare to select the largest number using nested if statements
#include <stdio.h> #include <stdlib.h> biggestNumber(int,int,int);//function prototype int main() { int a,b,c; printf("Enter the three numbers\n"); scanf("%d%d%d",&a,&b,&c); //read the numbers from user int result=biggestNumber(a,b,c);//function call printf("Biggest number is: %d\n",result); //display the output on the screen getch(); return 0; } int biggestNumber(int a,int b,int c){//function definition with parameter if(a>b) { if(a>c) return a; else return c; } else { if(b>c) return b; else return c; } }
When the above code is executed, it produces the following results
Enter the three numbers 45 89 67 Biggest number is: 89
This program allows the user to enter three numbers and compare to select the largest number using if-else-if statements
Program 2
#include <stdio.h> #include <stdlib.h> biggestNumber(int,int,int);//function prototype int biggestNumber(int a,int b,int c){//function definition with parameter int biggest; if(a>b && a>c) biggest=a; else if(b>a && b>c) biggest=b; else biggest=c; return biggest; } int main() { int a,b,c; printf("Enter the three numbers\n"); //reads the number for find largest scanf("%d%d%d",&a,&b,&c); int result=biggestNumber(a,b,c);//call the function printf("Biggest number is: %d\n",result); //display output on the screen getch(); return 0; }
When the above code is executed, it produces the following results
Enter the three numbers 34 56 43 Biggest number is: 56
