Hi everyone
I am not able to understand this program, It counts the repeated characters in the given string.
Can you tell me how it is doing so, what is the logic behind this.
What 65,91,97,123 denotes here ?
Thanks in advance!!!
Those numbers are character codes (ASCII). It only counts characters in the range 65 to 91 and 97 to 123 (inclusive), which are letters A to Z and a to z, and the characters [ and {. The fact that it includes [ and { is probably a bug. It should have been < 91 and < 123.
