C Program To Find Initials of a Name

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:

  1. Print the first character in the capital. 
  2. 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.
