int main(){ string s1 = "adedef" ; string s2 = "dek" ; int ans = s1.find_first_of(s2) ; //从s1的第二个字符开始查找子串s2 cout<<ans<<endl; system("pause"); } 其中find_first_of()也可以约定初始查找的位置: s1.find_first_of(s2 , 2) ; 3、find_last_of() 这个函数与find_...
int strncmp(const char *string1, const char *string2, size_t count); 比较字符串string1和string2大小,只比较前面count个字符. 比较过程中, 任何一个字符串的长度小于count, 则count将被较短的字符串的长度取代. 此时如果两串前面的字符都相等, 则较短的串要小. 返回值< 0, 表示string1的子串小于strin...
int strcmp(const char *string1, const char *string2); 比较字符串string1和string2大小. 返回值< 0, 表示string1小于string2; 返回值为0, 表示string1等于string2; 返回值> 0, 表示string1大于string2. int stricmp(const char *string1, const char *string2); 比较字符串string1和string2大小,和strc...
