Answer 2

Write a program in c to print first n prime numbers? // simple program to generate first ten prime numbers

#include

#include

void main()

{

int c,i,j,n;

clrscr();

for(i=2;i<30;i++)

{

c=0;

for(j=2;j

{

if(i%j==0)

{c=c+1;

}

}

if(c==0)

printf("%d",i);

}

getch();

}

Answer 3

#include<iostream>

#include<string>

#include<sstream>

unsigned input_num (std::string prompt)

{

unsigned num = 0;

while (true)

{

std::cout << prompt << ": ";

std::string input = "";

std::getline (std::cin, input);

std::stringstream ss (input);

if (ss >> num)

break;

std::cout << "Invalid input." << std::endl;

}

return (num);

}

int main()

{

while (unsigned num = input_num ("Enter a real number (0 to exit)"))

for (unsigned multiple=1; multiple<=10; ++multiple)

std::cout << num << " * " << multiple << " = " << num * multiple << std::endl;

}
