This program will accept input from user. and then by iterating each character from sentence it will count number of vowel and consonant. “A”, “E”,”I”,”O”,”U” either in upper or lower case character are vowels. Other than “A”, “E”,”I”,”O”,”U” all characters between A to Z are consonant.<\/p>\n\n\n\n

Program will read sentence in variable str. Every sentence end with ‘\\0’ so we are iterating sentence character by character till we not receive ‘\\0’. as we need to increment while count manually hence we are using chCount++; Each character is then getting compared with vowels and then associated variable counter is also getting incremented by one.<\/p>\n\n\n\n
