8.4 SIMPLE STRING PROGRAMS

8.4.1 Capitalize first character

Problem: Write a program to read a sentence (string) into an array and capitalize the first character of every word in the input.

Solution: We have to identify the first character of every word. We are going to scan the array character by character. When we encounter a blank, it means we are going to get a fresh word. This information is stored in a variable flag. To get uppercase character we use function toupper(ch) defined in<ctype.h>. See Program 8.2.
