Sorry if this question is answered already, but I didn't find a suitable answer. I am having a string expression in C# which I need to convert to an int or decimal value.
For example:
string strExp = "10+20+30";
the output should be 60.
how shall I do that???

In C, the atoi() function converts a string to an integer.
Description. The atoi() function converts a character string to an integer value. The input string is a sequence of characters that can be interpreted as a numeric value of the specified return type. The function stops reading the input string at the first character that it cannot recognize as part of a number.
The strtol library function in C converts a string to a long integer. The function works by ignoring any whitespace at the beginning of the string, converting the next characters into a long integer, and stopping when it comes across the first non-integer character.
