A wheel graph is obtained by connecting a vertex to all the vertices of a cycle graph. It is denoted by Wn, for n > 3 where n is the number of vertices in the graph. A wheel graph of n vertices contains a cycle graph of order n – 1 and all the vertices …
Write a program to count the number of articles in a string in C/C++. Example, Input An apple a day keeps the doctor away Output Number of “a” = 1 Number of “an” = 1 Number of “the” = 1 There are 3 articles in the English language – “a”, “an” and “the”. The problem …

Write a program in C/C++ to count the number of vowels and consonants in a string using pointers. Example, Input MyNameIsJohnSmith Output Consonants: 12 Vowels: 5 Steps Let str[] be the input string. Initialize c1 = 0 and c2 = 0. c1 stores the number of consonants and c2 stores the number of vowels. Read …

Write a program to count the number of distinct characters in a string in C/C++. Example, Input Willingly Output 6 Before we move further, we should know that there is a total of 128 characters in C/C++. Each character is represented by a unique integer value in the range [0, 127]. This numeric value is …

Write a program to print alphabets in reverse order in C/C++. The logic to print alphabets in reverse order is the same as printing alphabets in serial order. We print alphabets based on the fact that the ASCII value of all English alphabets is contiguous. The only difference is instead of iterating from ‘A’ to …
