The strcpy() built-in function copies string2, including the ending NULL character, to the location specified by string1. The string2 argument to strcpy() must contain a NULL character (\0) marking the end of the string. You cannot use a literal string for a string1 value, although stri...

你直接用string[0]=string1[0]是肯定可以的，我在tc2.0上面试过了 如下：void main(){ char a[5]="hello";char b[2]="an";a[0]=b[0];printf("%s",a);} 这个程序是可以通过的。用strcpy只是为了大量复制字符串时使用方便，其他数组都可以这样赋值为什么char型的数组不可以，是吧。像...
假设我们不使用c++提供的std::string, 而是使用char *指针来管理字符串资源, 大致实现如下 classperson{char*name;intage;public:// the constructor acquires a resource:// in this case, dynamic memory obtained via new[]person(constchar*the_name,intthe_age){name=newchar[strlen(the_name)+1];strcpy(...
}intmain(void){stringword;printf("Enter word to capitalize: ");scanf("%19s",word); word = Capitalize(word);printf("%s",word);return0; } strcpy()makes a copy, just like the name implies. it's perfectly legal to copy a string in to an array. ...
这里面是因为strcpy_s需要输入3个参数，而你只输入了2个参数。所以会报错。解决的方案有2种：（1）添加宏命令 在文件中添加 define _CRT_SECURE_NO_WARNINGS这样就忽略了使用新函数而报错了。（2）添加strcpy_s函数的输入参数。对于字符串拷贝函数来说 errno_t strcpy_s( char *strDestination, ...
编程题:编写一个函数string_copy()完成strcpy()的作用,并验证。 #include<stdio.h> void string_copy(char *s1,char *s2) { for(;*s2!='\0';s1++,s2++) *s1=*s2; *s1='\0'; } void main() { char str1[20],str2[]="I like C"; ...
In the C Programming Language, the strcpy function copies the string pointed to by s2 into the object pointed to by s1. It returns a pointer to the destination.SyntaxThe syntax for the strcpy function in the C Language is:char *strcpy(char *s1, const char *s2);Parameters...
strcpy, strncpy - copy a string SYNOPSIS #include <string.h> char *strcpy(char *restrict dest, const char *src); char *strncpy(char *restrict dest, const char *restrict src, size_t n); DESCRIPTION The strcpy() function copies the string pointed to by src, including the terminating ...
[ SIZE ] = "This is the source string"; char destination[ SIZE ] = "And this is the destination string"; char * return_string; printf( "destination is originally = \"%s\"\n", destination ); return_string = strcpy( destination, source ); printf( "After strcpy, destination becomes \...
