#includeIn this example, the SetToFormat function is used to set a BString object called "str" to a formatted string that includes the values of an integer and a float variable. The formatted string is then printed to the console using the printf function. In this case, the package/library used is likely the "BeAPI" or "InterfaceKit" library. Overall, the SetToFormat function is useful for formatting strings with data and is commonly used in BeOS and Haiku programming.#include int main(void) { BString str; int num = 42; float flt = 3.14159; str.SetToFormat("The answer is %d and the value of pi is %f", num, flt); printf("%s\n", str.String()); return 0; }
