C Program To Find The Largest Of Three Numbers.

In this program user is asked to enter three numbers and this program will find the largest number among three numbers entered by user. This program can be solved in more than one way.

Method 1:
#include <stdio.h>

int main(){
float a, b, c;
printf("Enter three numbers:\n");
scanf("%f %f %f", &a, &b, &c);

if(a>=b && a>=c)
printf("\nLargest number = %.2f", a);

if(b>=a && b>=c)
printf("\nLargest number = %.2f", b);

 if(c>=a && c>=b)
printf("\nLargest number = %.2f", c);

 return 0;
}

Method 2:
#include <stdio.h>

 int main(){
float a, b, c;
printf("Enter three numbers:\n");
scanf("%f %f %f", &a, &b, &c);

 if (a>=b) {
if(a>=c)
printf("\nLargest number = %.2f",a);
else
printf("\nLargest number = %.2f",c);
}

else {
if(b>=c)
printf("\nLargest number = %.2f",b);
else
printf("\nLargest number = %.2f",c);
}

 return 0;
}

Method 3:
#include <stdio.h>

int main(){
float a, b, c;
printf("Enter three numbers:\n");
scanf("%f %f %f", &a, &b, &c);

 if(a>=b && a>=c)
printf("\nLargest number = %.2f", a);

 else if(b>=a && b>=c)
printf("\nLargest number = %.2f", b);

 else
printf("\nLargest number = %.2f", c);

 return 0;
}

C Program To Check Whether A Number Is Palindrome Or Not.

This program takes an integer from user and the integer is reversed. If the reversed integer is equal to the integer entered by user then that number is a palindrome. If not that number is not a palindrome.   #include <stdio.h> int main()  { int num, temp, remainder, reverse = 0; printf("Enter an integer: "); scanf("%d", &num); /*  original number is stored at temp */ temp = num; while (num > 0)  { remainder = num % 10; reverse = reverse * 10 + remainder; num /= 10;   }

C Program To Convert Natural Numbers To Roman Numerals.

Roman Number System of representing numbers devised by the ancient Romans. The numbers are formed by combinations of the symbols I, V, X, L, C, D, and M, standing, respectively, for 1, 5, 10, 50, 100, 500, and 1,000 in the Hindu-Arabic numeral system. Natural numbers mean no negative numbers and no fractions, i.e. the whole numbers from 1 upwards: 1, 2, 3, and so on. Here is source code of the C program to convert natural numbers to Roman Numerals. It compiles and runs on any operating system. #include <stdio.h> void predigit(char num1, char num2); void postdigit(char c, int n); char romanval[1000]; int i = 0; int main() { int j; long number; printf("Enter any natural number: "); scanf("%d", &number);
