Answer:
The most straight forward way to do it: in general string are zero index based array of characters, so you need to get the length of the string, subtract one and that will be the last character, some expressions in concrete languages would be:
In Python:
name = "blair"
name[len(name) - 1]
In JavaScript:
name = "blair"
name[name.length - 1]
In C++:
#include <string>
string name = "blair";
name[name.length() - 1];
It’s a bot Bc when you do stuff you can believ it
Answer:
6 +4 + 6 +4
Explanation:
It will start from index 0 and wherever you find the character inside the indexOf methods then you will note it down.
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.
