Convert the C program given below which converts a length given in cm to inches to a C++ program.
Please Note that the input command in C++ is std::cin. This is a representation of the Keyboard.
e.g.
float data1;
int data2;
scanf("%f", &data1); --> std::cin >> data1;
scanf("%d", &data2); --> std::cin >> data2; You already know that printf() in C is std::cout in C++
e.g.
printf("Hello World") --> std::cout << "Hello World";
2.54cm = 1 inch
#include <stdio.h>
void main(void)
{
float cm, inches;
printf("Enter a length in cm : ");
scanf("%f",&cm);
inches = cm / 2.54;
printf("Length in inches is %f \n", inches);
} Convert the C program given below which calculates an employee's salary to a C++ program.
Input Type, Salary, otHours
Type = 1
OtRate = 1000
Type = 2
OtRate = 1500
Type = 3
OtRate = 1700
Please Note that the input command in C++ is std::cin. This is a representation of the Keyboard.
#include <stdio.h>
void main(void)
{
double salary, netSalary;
int etype, otHrs, otRate;
printf("Enter Employee Type : ");
scanf("%d", &etype);
printf("Enter Salary : ");
scanf("%f", &salary);
printf("Enter OtHrs : ");
scanf("%d", &otHrs);
switch (etype) {
case 1 :
otRate = 1000;
break;
case 2 :
otRate = 1500;
break;
default :
otRate = 1700;
break;
}
netSalary = salary + otHrs* otRate;
printf("Net Salary is %f ", netSalary);
}Convert the C program given below which calculates the Factorial of a number that you input from the keyboard to a C++ program.
Please Note that the input command in C++ is std::cin. This is a representation of the Keyboard.
#include <stdio.h>
void main(void)
{
int no;
long fac;
printf("Enter a Number : ");
scanf("%d", &no);
fac = 1;
for (int r=no; r >= 1; r--) {
fac = fac * r;
}
printf("Factorial of %d is %ld\n", no, fac);
}
Write a program to calculate the function called nCr which is defined as
nCr = n!/ r!(n−r)!
Where n! is the factorial of n.
Implement the functions
long Factorial(int no);
long nCr(int n, int r);
Do not modify the main function.
#include <iostream>
long Factorial(int no);
long nCr(int n, int r);
int main() {
int n, r;
std::cout << "Enter a value for n ";
std::cin >> n;
std::cout << "Enter a value for r ";
std::cin >> r;
std::cout << "nCr = ";
std::cout << nCr(n,r);
std::cout << std::endl;
}
