In the C Programming Language, the atoi function converts a string to an integer. The atoi function skips all white-space characters at the beginning of the string, converts the subsequent characters as part of the number.
num,str); } itoa()函数有3个参数：第一个参数是要转换的数字，第二个参数是要写入转换结果的目标字符串，第三个参数是转移数字时所用的基数。在上例中，转换基数为10。10：十进制；2：二进制... itoa并不是一个标准的C函数，它是Windows特有的，如果要写跨平台的程序，请用sprintf。 是Windows平台下...
C - Implementing a custom atoi() function. The atoi() function is used to convert a character string to an integer value. Code: #include<stdio.h>intmy_atoi(constchar*str){intresult=0;intsign=1;inti=0;// Check for leading sign characterif(str[0]=='-'){sign=-1;i++;}elseif(str...
The versions of these functions with the _l suffix are identical except that they use the locale parameter passed in instead of the current locale. For more information, see Locale.By default, this function's global state is scoped to the application. To change this behavior, see Global ...
