In C++, the string can be represented as an array of characters or using string class that is supported by C++. Each string or array element is terminated by a null character. Representing strings using a character array is directly taken from the ‘C’ language as there is no string type...

test1711.cpp:10:15: error: lvalue required as left operand of assignment N = 10; ~~^~~~ 📌 注意事项②:有些类型是不能作为非类型模板参数的,比如浮点数、类对象以及字符串。 非类型模板参数基本上都是整型,实际上也只有整型是有意义和价值的(可以这么理解)。
// Create an array of strings string cars[5] = {"Volvo","BMW","Ford","Mazda","Tesla"}; // Loop through strings for(inti =0; i <5;i++) { cout << cars[i] <<"\n"; } Try it Yourself » This example outputs the index of each element together with its value: ...
