program to be written in C language
Program 4 will prompt the user for one or two token, space delimited, inputs of at most 20 characters. If the user provides more than 20 characters before a newline is reached print the provided error message. If the number of tokens is incorrect, print the appropriate error message. If the input is correct, print the appropriate token types. Prompt the user for input (and provide output) until the user provides a single STR token "quit" (case insensitive). The program should quit immediately without output. 123 ERROR! Incorrect number of tokens found 1234567890123456789012345 ERROR! Input string too long. some 1 STR INT tuig STRExplanation / Answer
