Here, we will see how to find the initials of a name using a C program. Below are the examples:
Input: Geeks for Geeks
Output: G F G
We take the first letter of all
words and print in capital letter.Input: Jude Law
Output: J L
Approach:
- Print the first character in the capital.
- Traverse the rest of the string and print every character after space in capital letters.
Below is the C program to print the initials of a name:
C
// C program to print initials // of a name # include <stdio.h> # include <string.h> # include <ctype.h> // Function declaration void getInitials( char * name);
// Driver code int main( void )
{ // Declare an character array for
// entering names assuming the
// name doesn't exceed 31 characters
char name[50] = "Geeks for Geeks" ;
printf ( "Your initials are: " );
// getInitials function prints
// the initials of the given name
getInitials(name);
} void getInitials( char * name)
{ int i = 0;
if ( strlen (name) > 0 &&
isalpha (name[0]))
printf ( "%c " , toupper (name[0]));
while (name[i] != '\0' )
{
if ( isspace (name[i]) != 0)
{
while ( isspace (name[i]) &&
i <= strlen (name))
{
i++ ;
}
printf ( "%c " , toupper (name[i]));
}
i++;
}
printf ( "\n" );
} |
Output
Your initials are: G F G
Time Complexity: O(n), where n is the length of the string.
Auxiliary Space: O(1), as constant extra space is used.
