Question

Spend some time looking at open-source programs on Github. Find a piece of a C or C program on github that appears to display a significant amount of data locality. Provide the html browsable file URL and line numbers of the example. Justify why these lines demonstrate data locality. [Note that since this is real code, you may need to reference multiple files to demonstrate locality even in a single example.

Answer 1

I found that code

# This function adds two numbers

def add(x, y):

return x + y

# This function subtracts two numbers

def subtract(x, y):

return x - y

# This function multiplies two numbers

def multiply(x, y):

return x * y

# This function divides two numbers

def divide(x, y):

return x / y

print("Select operation.")

print("1.Add")

print("2.Subtract")

print("3.Multiply")

print("4.Divide")

# Take input from the user

choice = input("Enter choice(1/2/3/4): ")

num1 = float(input("Enter first number: "))

num2 = float(input("Enter second number: "))

if choice == '1':

print(num1,"+",num2,"=", add(num1,num2))

elif choice == '2':

print(num1,"-",num2,"=", subtract(num1,num2))

elif choice == '3':

print(num1,"*",num2,"=", multiply(num1,num2))

elif choice == '4':

print(num1,"/",num2,"=", divide(num1,num2))

else:

print("Invalid input")
