6.12) Since communications channels are often noisy, numerous ways have been devised to ensure reliable data transmission. One successful method uses a checksum. A checksum for a message can be computed by summing the integer codes of the characters in the message and finding the remainder of this sum divided by 64. The integer code for a space character is added to this result to obtain the checksum. Since this value is within the range of the displayable characters, it is displayed as a character as well. Write a program that accepts single-line messages ending with a period and displays the checksum character for each message. Your program should continue displaying checksums until the user enters a line with only a period. Note: When input is just a period, your program shouldn't calculate or display checkSum SAMPLE RUN #4: ./ChckSum Interactive Session Hide Invisibles Highlight: None Show Highlighted Only Enter the line to find-checkSum: ABCDEFGHIJKLMNOPQRSTUVWXYZ.+ checkSum: . - Enter the line.to find-checksum:abcdefghijklmnopqrstuvwxyz. checkSum: - Enter the line to find-checkSum:123456789. checksum: ++ Enter the line to find-checkSum:.+
