Answer:
Following are the function in C++ Programming language
bool hasRealSolution(int a,int b,int c) // function definition
{
if ((b*b)-(4*a*c)<0) // check condition
return false;
else
return true;
}
Explanation:
Following are the program of this question
#include <iostream> // header file
using namespace std; // namespace
bool hasRealSolution(int a,int b,int c); // prototype
bool hasRealSolution(int a,int b,int c) // function definition
{
if ((b*b)-(4*a*c)<0) // check condition
return false;
else
return true;
}
int main() // main function
{
bool x=hasRealSolution(1,2,4); // calling
cout<<x; // display the return value
return 0;
}
Output:
0
Following are the description of code:
- We declared a function i.e "hasRealSolution " of "bool" type.In this function there are three parameter is pass "a","b" and "c" of "int "type.
- In the if block we check the condition i.e if "b squared" minus 4ac is negative then it returns the false bool value otherwise it returns the true bool value.
- In the main function we call the function "hasRealSolution " by passing three integer values into that function and store their value in variable "x" of the bool type.
- Finally we print the value x in the main function.
