I. Introduction of Strings* In Java, a string type can be used to store"MJ"; There is no string of this type in the C language. In fact, the string is a sequence of characters, consisting of multiple characters, so in C, we can use a character array

Customizing a string to find standard library functions strstr ()#include #include char* mystrstr (char *str1,char *str2);int main (){char *str1 = "Hello worl world ld";Char *str2 = "World";Puts (Mystrstr (STR1,STR2));return 0;}Char *mystrstr (char *

When printing with printf, it turns out that the result is confusing if the data type is inconsistent with the type used for printing.This is because printf itself does not make the type conversion of the data, he just put the input in the given

first, arithmetic operationsThere are 34 types of operators in C, including common subtraction operations1. Addition Operation +Besides being able to do addition operations, it can also represent a plus sign: +5, +902. Subtraction operation-Besides

Lambda expressionRead Meng Yan a big blog (http://blog.csdn.net/myan/article/details/5877305), I decided to learn some main line content:①LAMBDA-expression②function/bind③ rvalue ReferenceThis article records the application of lambda expressions:

Why should I have an interface?An interface is a window in which a program communicates with other programs. For example, there is a TV, I do not need to know how it works, I just know to press the power button can turn on the TV, according to the
