substring c macros
You're confusing substring() and substr(): substring() expects two indices and not offset and length. In your case, the indices are 5 and 2, ie characters 2..4 will be returned as the higher index is excluded. How to check whether a string contains a substring in JavaScript ... 2 If you know the character also in the string from where you want to get the substring then you can use strstr function. It locates the substring. But if u do not know the character from where you want to retrieve then you can use the strcpy or strncpy to get the string as Eric has mentioned. O substring irá retornar à partir da posição informada no primeiro parâmetro até a posição informada no segundo, porém, o caractere da posição no segundo parâmetro não é incluído (ou seja, vai até o caractere anterior). How do I get a substring of a string in Python? - Stack Overflow
Syntax: string.slice(start, stop); Syntax: string.substring(start, stop); What they have in common: If start equals stop: returns an empty string If stop is omitted: extracts characters to the end of the string If either argument is greater than the string's length, the string's length will be used instead. Distinctions of substring(): If start > stop, then substring will swap those 2 ... The SUBSTRING function doesn't seem to be up to the task because it is position-based and the position of the underscore varies. I thought about the TRIM function (the RTRIM function specifically):
