x = 42;
int num = 0;
while (num <3)
Consele.writeline (x);
num++;
int x = 42; is just an int with an asigned value of 42
int num=0; is what initiate the count for the while loop
while (num < 3); means 0<3 true, 1< 3 true, 2<3 true, the loop end at 2 bc 3 <3 is false
consele.writeline (x) will display 42 while num < 3
num++ will execute and then add 1 to check if the while loop still true, but it stop at 2, bc 3 makes it false.
so the consele.write will write 42 three times. x=42, remember the (x)

2 odpowiedziwhy does this code output that there is an error because the else statement doesn't have a corresponding if statement?. How do i correct this?
#include <iostream>
using namespace std;
int main() {
int a;
for (int x =0; x<5;x++){
cin>>a;
if (a<1){
cout<<"a cannot be less than 1\n";
}
else if (a>10){
cout <<"a cannot be greater than 10\n";
}
}
else{
cout<<"code can run now"<<endl;
}
return 0;
}

using namespace std;
int sum(int a, int b=42) {
int result = a + b;
return (result);
}
int main() {
int x = 24;
int y = 36;
//calling the function with both parameters
int result = sum(x, y);
cout << result << endl;
//calling the function without b
result = sum(x);
cout << result << endl;
return 0;
}
why is da last function cout 66 and not 48 isn't it suppose to add 24+24?

4 odpowiedziWrite and test a program that solves quadratic equations. A
quadratic equation is an equation of the form ax2+ bx + c =0 ,where a,b and c are given coefficient and x is the unknown The coefficients are real number inputs ,so they should be declared of type float or double Since quadratic equations typically have two solutions ,use x1 and x2 for the solutions to be output These should be declared of type double to avoid inaccuracies from round-off error

4 odpowiedzidef add(x, y):
return x + y
def do_twice(func, x, y):
return func(func(x, y), func(x, y))
a = 5
b = 10
print(do_twice(add, a, b))
Please explain step by step
Which is caller here?
Explain the 3rd and 4th line ?
why in 4th line we write add(add(x,y),add(x,y)) which is function of 1st line ?
how can we write function after return statement insted of (x+y+x+y )=30?

2 odpowiedziTo bind two things of similar origin but separate identities together as one unit with ability to function independently as long and the unit is not corrupted. How to set x to get y and become z permanently and protect the unit from corrupt or deviation or denying or hiding while z securely functions actively is the purpose.
