环境:dev-c++
源代码:
#include <iostream>
#include <cstdlib>
using namespace std;
main()
{
int i1=123,i2,i3;
float f1;
char c1[20]="234.45",c2[20];
string s1="456",s2;
i2=atoi(c1); //将字符数组转化为整数
f1=atof(c1); //将字符数组转化为浮点型
itoa(i1,c2,10); //将整型转化为字符数组 10为10进制的意思
cout<<"字符数组转化为整型: "<<i2<<endl;
cout<<"字符数组转化为浮点型: "<<f1<<endl;
cout<<"整型转化为字符数组: "<<c2<<endl;
strncpy(c2,s1.c_str(),s1.length());//字符串转化为字符数组
i3=atoi(c2);
cout<<"字符串转化为整型: "<<i3<<endl;
system("pause");
}
