十六进制转换为十进制C程序设计，函数实现，通俗易懂-Hexadecimal to decimal C programming, function implementation, easy to understand

本计算器可以进行简单的四则运算（加、减、乘、除）但仅限于十进制下，还可以进行（八进制，十进制，十六进制）之间的相互转换-This calculator can be a simple four operations (addition, subtraction, multiplication, in addition to the mutual conversion between) but only under the decimal (octal, decimal, hexadecimal)

vb编写的进制转换程序源码，可以实现十六进制转换为二进制、二进制转化为十六进制、十六进制转化为十进制、八进制转化为十进制、二进制转化为十进制、十进制转化为十六进制、十进制转化为八进制、十进制转化为二-vb prepared by the hex conversion program source code, can be achieved hex conversion to binary, binary into hexadecimal, converted to hex decimal, oc
