Question

1.Write a program to find largest number among three number. Also, design flowchart of the program. 

2. Write a C Program to Calculate the Power of a Number. [Hint Use math.h library and pow() function ]

Answer 1

1.
#include <stdio.h>
#include <math.h>
//The start point of the program
int main() {
	int number1;
	int number2;
	int number3;
	int largest;
	//get the first number from the user
	printf("Enter the first number: ");
    scanf("%d", &number1);
	//get the second number from the user
	printf("Enter the second number: ");
    scanf("%d", &number2);
	//get the third number from the user
	printf("Enter the third number: ");
    scanf("%d", &number3);
	largest=number1;
	//Find the largest number
	if(number1 < number2) {
		largest = number2;
	}else {
		largest = number1;		
	}
	if(largest < number3) {
		largest = number3;
	}   
	// Print the largest number
	printf("The largest number among three number is: %d",largest);
	//delay
	getchar();
	getchar();
    return 0;
}

#include <stdio.h>
#include <math.h>
//The start point of the program
int main() {
	int number;
	int exponent;
	unsigned long power;
	//get the number from the user
    printf("Enter the number: ");
    scanf("%d", &number);
	printf("Enter an exponent: ");
    scanf("%d", &exponent);
	power=pow(number*1.0,exponent);
	//display result
	printf("The power of a number %d = %u",number,power);
	//delay
	getchar();
	getchar();
    return 0;
