飞机飞行轨迹仿真，可根据自己需要改数据，源代码是网上找的，原地址找不到了，觉得之前的数据不是很合理，已经做了许多改动，将飞行速度降到了0.8马赫左右，飞行高度降到了8000左右，大家可以根据自己的需求自行更改。、

this code is written to convert the decimal number to hexadecimal number in sixteen bit format. the decimal numbers are stored in a text file and after conversion to the hexadecimal format data are stored in a seperate file data that is written will be in the coe file format.function fscanf is used to read the txt file and function fprintf is used to to write a file in a particular location .function dectohex is used for decimal to hexadecimal conversion.
