Syntax:
int sprintf(char *str, const char *string,...);
Return:
If successful, it returns the total number of characters written excluding null-character appended in the string, in case of failure a negative number is returned .
sprintf stands for “String print”. Instead of printing on console, it store output on char buffer which are specified in sprintf.
C
// Example program to demonstrate sprintf() #include <stdio.h> int main()
{ char buffer[50];
int a = 10, b = 20, c;
c = a + b;
sprintf (buffer, "Sum of %d and %d is %d" , a, b, c);
// The string "sum of 10 and 20 is 30" is stored
// into buffer instead of printing on stdout
printf ( "%s" , buffer);
return 0;
} |
Output
Sum of 10 and 20 is 30
Time Complexity: O(n), where n is the number of elements being stored in buffer.
Auxiliary Space: O(n), where n is the number of elements being stored in buffer.
