Where is printf in c

The value is not truncated even if the result is longer. A precision of 0 means that no character is written for the value 0. For a , A , e , E , f and F specifiers: this is the number of digits to be printed after the decimal point by default, this is 6.

For g and G specifiers: This is the maximum number of significant digits to be printed. For s : this is the maximum number of characters to be printed. By default all characters are printed until the ending null character is encountered.

If the period is specified without an explicit value for precision , 0 is assumed. The precision is not specified in the format string, but as an additional integer value argument preceding the argument that has to be formatted. The scanf function reads formatted input from the standard input such as keyboards.

When the user enters an integer, it is stored in the testInteger variable. When a character is entered by the user in the above program, the character itself is not stored.
