Are you really trying to convert the letters s t and r to an int? atoi() returns 0 if the characters in the string do not represent an int value.

A better choice is a string with "123".

atoi converts till it encounters ant non numerical characters, ie till someting other then 0 to 9, is encountered. here a is not integer so atoi stops conveerting hence returns zero
