Answer:(1) To manage the computer's resources, which includes central processing unit, memory, disk drives, and printers, (2) To establish a user interface
(3)To execute and provide services for applications software.
The old mainframe computers have
(1) low memory sizes
(2) slower connectivity speed
(3) Larger sizer
(4) low sophistication.
Explanation: Operating system is a system software that manages the computer resources,helps to establish user interface and it helps to provide services for application softwares.
Operating system software includes WINDOWS X,WINDOWS 7,WINDOWS 8,LINUX,etc.
Mainframe computers are computers used by large multinational companies for processing bulk data. Old mainframe computers were produced by IBM(INTERNATIONAL BUSINESS MACHINE) in the year 1952 they are classed two scientific and commercial mainframe computers with different information although they had some incompatibilities. Old mainframe computers are large in size with low processing speed, sophistication and storage compared to present day system.
Answer:
#include <bits/stdc++.h>
using namespace std;
void funct(){
string name;
cout<<"enter the string: ";
cin>>name;
reverse(name.begin(), name.end());
cout<<"The string is : "<<name<<endl;
}
int main()
{
funct();
return 0;
}
Explanation:
create the function funct() with return type void and declare the variable type string and print a message for asking to used enter the string.
The string enter by user is store in the variable using cin instruction.
after that, we use a inbuilt function reverse() which takes two argument.
firs argument tell the starting point and second index tell the ending point. then, the reverse function reverse the string.
name.begin() it is a function which return the pointer of first character of string.
name.end() it is a function which return the pointer of last character of the string.
finally, print the reverse string.
for calling the function, we have to create the main function and then call the function.
