Write a program to check if user inputs "yellow"
Answer:
In Python:
col = input("Enter Color: ")
if col == "yellow":

col = input("Enter Color: ")
This checks if color is yellow
if col == "yellow":
If true, this prints true
print("True")
If otherwise, this prints false
else:
print("False")
Answer:
zeroIt(&x);
Explanation:
The statement that sets the value stored in x to zero by invoking the function zerolt is given below
zeroIt(&x);
The zeroIt function is also given below for better understanding.
void zeroIt(int *x) {
*x = 0;
}
As seen, the function takes an argument with integer variable type, which is a pointer, denoted by the asterisk symbol (*x).
The ampersan sign (&x) is used to access the variable whose value can then be stored.
