int age = 23 ;
char str[100];
sprintf( str , "My age is %d",age);
puts(str);

Analysis of Source Code : - Just keep in mind that

Assume that we are using printf then we get output “My age is 23″
What does printf does ? —- Just Print the Result on the Screen
Similarly Sprintf stores result “My age is 23″ into string str instead of printing it.
