The CPU, or central processing unit, is the hardware that takes most of the load when running a program. It will perform complex calculations and execute every instruction as the program continues.
The GPU, or graphics procession unit, is the hardware that could also play a major roll in calculating the instructions to execute a program, though this depends on how graphically intensive the program is. For example, games would use a lot more GPU power than say a simple calculator application.
Answer:
Iterative
Explanation:
is the model that emphasizes small revisions, unlike waterfall which is in a linear sequential flow.
Answer:
The Ribbon is composed of three parts: Tabs, Groups, and Commands.
Answer:
#include <iostream>
using namespace std;
int main()
{
string s;
cin>>s; //reading string
int i,j;
bool has_dups=false;
int n= s.length();
for(i=0;i<n;i++) //to check for duplicate characters
{
for(j=0;j<n;j++)
{
if(j!=i && s[i]==s[j]) //to check if it is matched with itself
{
has_dups=true; //if true no need to check others
break;
}
}
}
cout<<has_dups;
return 0;
}
OUTPUT :
California

Explanation:
Above program finds if a character repeat itself in the string entered by user.
Answer:
UTF-8 and ASCII both are the character encoding.
In a system,every character has some binary representation,these are the method to encode them.Earlier only ASCII was there, for every character it uses 8 bits to represent.In ASCII only 8 bytes were there i.e 2^8 that is 256.We can't represent number beyond than 127 so it generate a need for other encoding to get into,these drawbacks lead to Unicode,UTF-8.
As ASCII codes only uses a single byte,UTF-8 uses upto 6 bytes to represent the characters.So we can save characters which are as long as 2^48 characters. We can read this encoding easily by the help of shift operators and it is also independent of byte order.
As messages on internet were transferred over 7 bit ASCII messages,so many mail servers removed this encoding.
