memcpy function is used to copy memory area. Syntax ------ void *memcpy(void *dest, const void *src, size_t n); *dest is a destination string. *src is a source string. n is a number of characters to be copied from source string. Example: #include #include main() { char src[]="Hello World"; char des[10]; memcpy(des,src,5); printf("des:%s\n",des); //It will contain the string "Hello". }
They do different things, so they are uncomparable.PS: strcpy can be implemented with strlen+memcpy:char *strcpy (char *dest, const char *src){size_t len;len= strlen (src);memcpy (dest, src, len);return dest;}
No. Syntax is/are the rules of the language, tags are part of the syntax.
memcpy()
Syntax is essential to any form of language. Without syntax, there is no setting, there is no way to explain it and no language. Language and setting are both comprised with syntax.
unsigned char * memcpy(unsigned char * s1, unsigned char * s2, long size) { long ix; s1= (char *)malloc(sizeof(strlen(s2))); for(ix=0; ix < size; ix++) s1[ix] = s2[ix]; return s1; }
The memcpy library is used in computer programming to copy the value of numbers from a source to the memory block destination. Memcpy is frequently used in the C++ programming language.
memcpy is general purpose copy. and strcpy is specific for string copying. strcpy will copy the source string to destination string and terminate it with '\0' character but memcpy takes extra argument which specifies the number of bytes to copy.memcpy will not handle copying of overlapping memory. use memove instead.

Not possible; syntax cannot be avoided. (Syntax errors can be though.)
Common questions about syntax in programming languages include: "What is syntax and why is it important?", "How does syntax differ between programming languages?", "What are some common syntax errors and how can they be avoided?", and "How can I improve my understanding of syntax in a programming language?"

memmove handles the case where the source memory and destination memory overlap.

There are no antonyms of syntax. It's a noun.
