== == What is printf in c or prototype of printf with example (q) What is prototype of printf function ? Explain each term. Ans: Prototype of printf function is : int printf( const char *format ,…) Explanation of each term : Parameter of printf function is : (three continuous dots) : It is called ellipsis. It indicates the variable number of arguments. Example of ellipsis: #include void ellipsis(int a,...); void main() { int a=5,b=10; clrscr(); ellipsis(a,b); getch(); } void ellipsis(int a,...) { printf("%d ",a); } Output:5 So printf function can have any number of variables as an argument.

What is the difference between echo and print and printf in PHP?
The print function is slightly more dynamic than the echo function by returning a value, and the echo function is slightly (very slightly) faster. The printf function inserts dynamic variables/whatever into wherever you want with special delimiters, such as %s, or %d. For example, printf('There is a difference between %s and %s', 'good', 'evil') would return 'There is a difference between good and evil'.
