Answer:

inFile.open("progdata.dat");

Explanation:

This command opens the file which is passed to it as an argument. We are quite used to the C++'s cin and cout functions contained in iostream library for reading and writing data, however, when working will real-life stuff, we find ourselves working with huge data saved as separate files and require our programs to read them, manipulate them and possibly write back to the files... The first operation usually carried out before a file can be read or written to is open

Assume that month is an int variable whose value is 1 or 2 or 3 or 5 ... or 11 or 12. Write an expression whose value is "jan" o
Tamiku [17]

Answer:

The code is given below

Explanation:

The correct syntax would be to place appropriate parenthesis.

(month==1?"jan":(month==2?"feb":(month==3?"mar":(month==4?"apr":(month==5?"may":(month==6?"jun":(month==7?"jul":(month==8?"aug":(month==9?"sep":(month==10?"oct":(month==11?"nov":"dec")))))))))));

Similarly, you can also use the following code:

String[] months = { "jan", "feb", "mar", "apr", "may", "jun", "jul", "aug", "sep", "oct", "nov", "dec" };

int month = 1;

String monthDescription = months[month - 1];

andriy [413]

Answer:

#include<bits/stdc++.h>

using namespace std;

int main()

{

   string st;

   getline(cin,st);

   int i=0;

   while(i<st.length())

   {

       if(isupper(st[i]))

       {

           st.erase(st.begin()+i);

           continue;

       }

       i++;

   }

   cout<<st<<endl;

   return 0;

}

Explanation:

I have included the file bits/stdc++.h which include almost most of the header files necessary.

For taking the input as a string line getline is used.

For checking the upper case isupper() function is used. cctype header file contains this function.

For deleting the character erase function is used.
