Question

this assignment should be delivered 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. > 1 2 3 ERROR! Incorrect number of tokens found. > 12345 678901 23456789 012345 ERROR! Input string too long. > Some 1 STR INT > tuiq STR. >QuIt
