c – 查找以另一个文本开头的文本

C中有什么方法可以在另一个文本中找到一个文本？

例如,text =“abaHello”,textneedtoSearch =“Hello”;.

如果文本包含“Hello”,返回true,否则返回false.

解决方法

Character and string searching functions

`char *strstr( const char *s1,const char *s2)`

returns a pointer to the first
instance of string s2 in s1. Returns
a NULL pointer if s2 is not
encountered in s1.

另外,

int strcmp(const char *s1,const char *s2);

strcmp compares the string s1 to the string s2. The function returns 0 if they are the same,a number < 0 if s1 < s2,a number > 0 if s1 > s2.

This is one of the most commonly used
of the string-handling functions.
