I'm totally puzzled
string temp = "73";
int tempc0 = Convert.ToInt32(temp[0]);
int tempc1 = Convert.ToInt32(temp[1]);
MessageBox.Show(tempc0 + "*" + tempc1 + "=" + tempc0*tempc1);
I would expect: 7*3=21
But then I receive: 55*51=2805
861
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.
In Java, we can convert the Char to Int using different approaches. If we direct assign char variable to int, it will return the ASCII value of a given character. If the char variable contains an int value, we can get the int value by calling Character.
We can convert char to int by negating '0' (zero) character. char datatype is represented as ascii values in c programming. Ascii values are integer values if we negate the '0' character then we get the ascii of that integer digit.
That is the ASCII value for the character 7 and 3. If you want number representation then you can convert each character to string and then use Convert.ToString:
string temp = "73";
int tempc0 = Convert.ToInt32(temp[0].ToString());
int tempc1 = Convert.ToInt32(temp[1].ToString());
MessageBox.Show(tempc0 + "*" + tempc1 + "=" + tempc0*tempc1);
55 and 51 are their locations in the ascii chart. Link to chart - http://kimsehoon.com/files/attach/images/149/759/007/ascii%281%29.png
try using int.parse
