C++ programming:program to accept your name and print initials:how to display initials:name initials sample in C

In this tutorial, you will find a C++ program which accepts a name and prints initials for example if the input is "Vidhu Vinod Chopra", program will print "V.V.Chopra".

Following is a C++ program to accept a name and then print its initials. For Example If the input is "Mohandas Karamchand Gandhi"

This program will display M.K.Gandhi

Program Explanation:

Logic:

first print the first character by cout<<arr[0] and a dot by cout<<"." Then a loop runs till end of string and if it finds space, the next character is printed and a dot is printed. So in the above exmple if we input Mohandas Karamchand Gandhi, the output is M.K.G. Now a loop runs in array to go back till it finds a space. Then the statement cout<<\b\b" at line 22 erases 2 characters backside. It erases "G." Now a loop again runs from next character of the the last space till the end of the string. In our example it starts from G and prints Gandhi.

Line 9: input through gets() because cin does not input space

#include<iostream.h>
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
char arr[40];
cout<<"Enter The Name "<<endl;
gets(arr);
cout<<arr[0]<<".";
for(int i=0;arr[i]!='\0';i++)
{
  if(arr[i]==' ')
  {
  cout<<arr[i+1]<<".";
  i++;
  }
}
if(arr[i]=='\0')
{
for(;arr[i]!=' ';i--);
  cout<<"\b\b";
  i++;
  for(;arr[i]!='\0';i++)
  {cout<<arr[i];}
}
getch(); 
}

Output

Enter The Name
Mohandas Karamchand Gandhi

M.K.Gandhi
