Expert's answer

#include <iostream>

int main()

{

//show message and enter first leg of triangle

std::cout <<"Enter first leg of right triangle\n";

float a=0;

std::cin >>a;

//show message and enter second leg of triangle

std::cout <<"Enter second leg of right triangle\n";

float b=0;

std::cin >>b;

float area=0;

//if input correct then calculate an area else show error message

if( ( a>0 ) && (b>0) )

{

area=a*b*0.5;

std::cout <<"Area=" <<area <<"\n";

}

else

{

std::cout <<"Input error!\n";

}

return 0;

}

int main()

{

//show message and enter first leg of triangle

std::cout <<"Enter first leg of right triangle\n";

float a=0;

std::cin >>a;

//show message and enter second leg of triangle

std::cout <<"Enter second leg of right triangle\n";

float b=0;

std::cin >>b;

float area=0;

//if input correct then calculate an area else show error message

{

area=a*b*0.5;
