Answer:
Hence, <u>Input Validation</u> is the process of inspecting data that has been input to a program to make sure it is valid before using it in a computation.
Explanation:
The input should be validated before further processing to avoid problems in execution of program afterwards.
The process of input validation is defined to make sure that the input is valid.
Hence, <u>Input Validation</u> is the process of inspecting data that has been input to a program to make sure it is valid before using it in a computation ..
Answer:
The answer is "Option C".
Explanation:
Relational expression are one or more variable and maybe even values, which operators have linked together. It is also known as the process, which is used to calculate the outcome, that is generated by the relational expression. These words are typically designed to answer the questions in boolean values, and other options were not correct, that can be described as follows:
- In option A, This process is used to perform the mathematical operation, that's why it is not correct.
- Option B and Option D both is used to compare values, that's why it is not correct.

Answer:
// code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
int length=10,height=7,width=5;
// find the volume of
int vol=length*height*width;
// find the surface area
int sa=2*(length*width+length*height+height*width);
// find the perimeter
int peri=4*(length+width+height);
// print the volume
cout<<"Volume is: "<<vol<<" cm^3."<<endl;
// print the surface area
cout<<"Surface area is: "<<sa<<" cm^2."<<endl;
// print the perimeter
cout<<"Perimeter is: "<<peri<<" cm."<<endl;
return 0;
}
Explanation:
Declare and initialize length=10, width=5 and height=7.calculate volume by multiply length, width and height and assign to variable "vol".Then find the surface area as 2*(length*width+length*height+height*width) and assign it to variable "sa".Then find the perimeter as 4*(length+width+height) and assign to variable "peri". Print the volume, perimeter and surface area.
Output:
Volume is: 350 cm^3.
Surface area is: 310 cm^2.
Perimeter is: 88 cm.
