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". }

What is better strcpy or memcpy?
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;}
Are HTML tags and syntax the same?
No. Syntax is/are the rules of the language, tags are part of the syntax.
Which function is the correct choice for moving blocks of binary data that are of arbitrary size and position in memory?
memcpy()
How does syntax affect setting?
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.
Code to implement memcpy in c?
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; }
What is the memcpy library used for in computer programming?
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.
What are the differences between memcpy vs strcpy?
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.

How do you prevent syntax in programming?
Not possible; syntax cannot be avoided. (Syntax errors can be though.)
What are some common questions about syntax in programming languages?
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?"
Which function is the correct choice for moving blocks of binary data that are of arbitrary size and position in memory?
memcpy()
What is the difference between the functions memmove and memcpy?
memmove handles the case where the source memory and destination memory overlap.

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