Define a function called hasRealSolution that takes three parameters containing integer values: a, b, and c. If "b squared" minus 4ac is negative, the function returns False otherwise, it returns True.

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 / / 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<
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.
