摘要：
C/C++中int/long/float/double数值类型与字符串互相转换[总结]memcpy方法可以实现将int等保存到字符类型的数组中。示例：long long_data=-9828;unsigned char data[4];memcpy(data,&t,4); //将long类型的数据用4个char保存。long my_long_data=0;memcpy(&tt,data,4);//从4个char中还原出long类型数据。一、int/long/float/double转字符串方法1：itoa, ltoa（a表示array数组的意思）头文件：stdlib.h示例：i 阅读全文
