Question

Write a C program that inputs a line of text

1) use standard input/output library function to get user input
2) print it out with uppercase
3) reverse the string and print it out
4) uses function strtok to count the total number of words. Assume that the words are separated by either spaces.

Answer 1

The question requires writing a C program to read a line of text, convert it to uppercase, reverse it, and count the number of words using the strtok function.

Step-by-step explanation:

The subject of this question is a C programming task that involves several operations on a string input by the user. The program should meet the following criteria:

• Get user input using standard input/output library functions
• Print the input string in uppercase
• Reverse the string and print it
• Count the total number of words using the strtok function, assuming words are separated by spaces

To achieve this, aside from the main function, dedicated functions for transforming the string to uppercase, reversing the string, and counting words can be written. The strtok function is a standard library function in C that can be used to split strings into tokens, which can be counted to determine the number of words.
