لو سمحتوا ممكن مساعده

السلام عليكم,

هده مبادرة لأجل ما طلبت فهي شغالة مبدئيا وقد لا تتوافق كل الشروط المطلوبة وإنما يمكن تغييرها بسهولة لتتجاوب مع ما تريد.

هاهو الكود هنا وفي الملف المرافق:

#include <iostream.h>
#include <stdlib.h>
#include <time.h>
#include <math.h>

int Sum(int,int);
int Diff(int,int);
float Mult(int,int);
void main()
{
	srand( (unsigned)time( NULL ) );
	int number1,number2;
	number1=rand()%100;
	number2=rand()%30;
	int s=Sum(number1,number2);
	int d=Diff(number1,number2);
	float prod=Mult(s,d);
	cout << "The first number is : " <<number1 <<"\n";
	cout << "The second number is : " << number2 << "\n";
	cout << "the Sum is : "<< s <<"\n";
	cout << "The Diff is : " << d<<"\n";
	cout <<"The product is : "<< prod << "\n";
	if(d >=0)
	{
  double square=sqrt(d);

  cout << "The squre rooot is : " << square << "\n";
	}
	else
	{
  cout <<"Can't calculate The Sqrt of negative numbers \n";
	}

}

int Sum(int x,int y)
{
	return x+y;
}
int Diff(int x,int y )
{
	return x-y;
}
float Mult(int x,int y)
{
	return (float)x*y;
}

مع متمبياتي لك بالتوفيق.

شكرًا جزيلاً chik

لوسمحتوا (والله مستحيه منكم) بدون كلافه عندي سؤالين ومحتاجه أعرف الجواب

Exercise 1

Given the following table of sin(θ), where θ is given in degrees

)the table is in the file)

Write a C++ program to print the above table in a file sin.out. Use the table to find the sin of, for example, 35 degrees, you would look for the row starting with 30, then move across to the column for 5, giving you a value of 0.574.

Note about sin: The prototype for the sin function is in the < cmath > header file. The argument of sin is given in radians, not degrees.

radians = degrees × Pi /180

where Pi is approximately 3.1415926.

Note: You may notice slight differences in the results between your program and the above table. This is not very significant.

Exercise 2

Write a program that performs the following functions:

• (a) Writes a function with the prototype:

bool isNegative(float)

that returns true if the given value is less than 0 and returns false if the given value is not less than 0.

• (B) Writes a function with the prototype:

float validSqrt(float)

that returns the sqrt of the given value if the value is not negative and returns -1.0 if the value is

negative. This function must use the function isNegative of part (a).

• © Your program should test the function validSqrt. The program should read values from a file

input.dat and output the square root or an error message as is appropriate in a file result.out

Example:

4

The square root of 4 is 2.

0

The square root of 0 is 0.

-3

The square root of -3 is not possible.
