编写一个高效的函数来实现strcmp()C中的函数。标准strcmp()函数比较两个字符串并返回一个整数,表示它们之间的关系。 的原型strcmp()是: int strcmp(const char* X, const char* Y); 这strcmp()函数返回一个大于、等于或小于零的整数,相应地,因为 X 指向的字符串大于、等于或小于 Y 指向的字符串。
intstrcmp(constchar* str1,constchar* str2 ); Compare two strings 比较两个字符串 Compares the C stringstr1to the C stringstr2. str1与str2进行比较 This function starts comparing the first character of each string. If they are equal to each other, it continues with the following pairs unti...
The syntax for the strcmp function in the C Language is: int strcmp(const char *s1, const char *s2); Parameters or Arguments s1 An array to compare. s2 An array to compare. Returns The strcmp function returns an integer. The return values are as follows: ...
So using the function strcmp with character arrays that do not store strings invokes undefined behavior. You should write at least char inst1[] = { "A" }; char inst2[] = { "A" }; that is to initialize the arrays with string literals. Pay attention to that for example the string ...
I am having trouble with comparing strings (char arrays) using the strcmp() function. I have been at it for hours, but I still don't understand what I am doing wrong. Does it have to do with pointers? Here my my code: #include <stdio.h> #include <string.h> int main(){ char...
strcmp(dest,src2)) printf("dest is equal to src2"); else printf("dest is %s",dest); printf("%s\n", dest); getch(); return 0; } 运行结果是: Aloha dest is equal to src2 1.3.3 复制memcpy 函数原型:void memcpy(void destin, void *source, unsigned n) 函数功能:从source所指的...
C 库函数 int strcmp(const char *str1, const char *str2) 把str1 所指向的字符串和 str2 所指向的字符串进行比较。声明下面是 strcmp() 函数的声明。int strcmp(const char *str1, const char *str2)参数str1 -- 要进行比较的第一个字符串。 str2 -- 要进行比较的第二个字符串。
strcmp(Words[wordCount],temp);或strcmp(Words[wordCount],&temp[0]);尽管我所说的可能有点混乱,但...

C Library - strcmp() function - The C Library strcmp() function is used to compare two strings. It checks each character in the string one by one until it finds a difference or reaches the end of the one string. Additionally, the strings comparison is ba
