Ideas in this flowchart

Formatted input and output functions process strings
sscanf() parses values from an input string
Its first argument is the string containing the value to parse
Its second and third arguments match scanf(): a format string and variables passed by reference
sprintf() is similar to printf(), but produces formatted text in a string
Instead of standard output, sprintf() places the result in a string
The example initializes x to 10, y to 3.14, and allocates space for s
sprintf() formats x and y and stores the result in s
The resulting string is "The value of x is 10, y = 3.140000."

"The sscanf() function differs in its first argument: the string that contains the value you want to parse. Otherwise, the second two arguments are as in scanf(): the format (as a string) and the variable(s) that the results should be stored in (passed by reference). Likewise, there is a companion sprintf() which is similar to the printf() function, but instead of printing to the standard output, it “prints” to the string. That is, the result is placed in a string.\n\nint x = 10;\n\ndouble y = 3.14;\n\nchar *s = (char *) malloc(sizeof(char) * 50);\n\nsprintf(s, \"The value of x is %d, y = %f.\", x, y);\n\n// s now contains \"The value of x is 10, y = 3.140000.\""
