Answer and explanation :
the three control problems associated with competing process are
- MUTUAL EXCLUSION : We know that some resources are shareable and some are not shareable. which means only one process can access the resource at a time this type of resources are called critical resources this code can be access at only one process at a time. the other process if required to access should not be allowed
- DEADLOCK: this hold the process without complete for example suppose there are two resources R1 and R2 and two process P1 and P2 and P1 use R1 and P2 use R2 but after some time when P1 needs R2 but R2 is not available as it is used by P2 so the all process will be on hold
- STARVATION : when priorities are given to the process as high priorities and low priorities. And high priorities process always competing then low priorities process have to wait for very long time this is called starvation
Answer:
An LS button
Explanation:
It appears on the (structure line 3)on the structure line, place your cursor in the <u>whi</u><u>te</u> field to the right of the E button (Recall that the E button represent the entry test).
Answer:
#include <iostream>
using namespace std;
class Str{ ///baseclass
public :
string super_str;
string getStr()
{
return super_str;
}
void setStr(string String)
{
super_str=String;
}
};
class str : public Str{ //inheriting Str publicly
public :
string sub_str;
string getstr()
{
return sub_str;
}
void setstr(string String)
{
sub_str=String;
}
bool notstartswith()
{
int n=sub_str.length(); //to find length of substr
bool flag=false;
for(int i=0;i<n;i++) //Loop to check beginning of Str
{
if(super_str[i]!=sub_str[i])
{
flag=true;
break;
}
}
return flag;
}
};
int main()
{
str s; //object of subclass
s.setStr("Helloworld");
s.setstr("Hey");
if(s.notstartswith()==1) //checking if str is substring of Str
cout<<"Str does not start with str";
else
cout<<"Str starts with str";
return 0;
}
OUTPUT :
Str does not start with str
Explanation:
Above program is implemented the way as mentioned. for loop is being used to check the beginning of the str starts with substring or not.
Answer:
Following are the program in the Python Programming Language.
#set the infinite while loop
while(True):
#get string input from the user
name=input()
#get integer input from the user
num=int(input())
#set the if statement to break the loop
if(num==0):
break
#otherwise, print the following output
else:
print("Eating {} {} a day keeps the doctor away.".format(num, name))
<u>Output</u>:
oranges
5
Eating 5 oranges a day keeps the doctor away.
apple
0
Explanation:
<u>Following are the description of the program</u>:
- Set the loop that iterates at infinite times and inside the loop.
- Declare two variables which are 'name' that get string type input from the user and 'num' that get integer type input from the user.
- Set the if conditional statement for break the infinite while loop.
- Otherwise, it prints the following output.
