List of Common C Format Specifiers

Examples of C Format Specifiers

1. Character Format Specifier - %c

The %c format specifier is used for the char data type in C. It works for both input and output formatting.

// C Program Example#include int main() {char c;scanf("%c", &c);printf("Entered character: %c", c);return 0;}

2. Integer Format Specifier (signed) - %d

For signed integers, the %d format specifier can be used with input and output functions in C.

// C Program Example#include int main() {int x;scanf("%d", &x);printf("Printed using %%d: %d\n", x);return 0;}

3. Unsigned Integer Format Specifier - %u

The %u specifier handles unsigned integers. A negative integer passed with %u converts to its first complement.

// C Program Example#include int main() {unsigned int var;scanf("%u", &var);printf("Entered Unsigned Integer: %u", var);return 0;}

4. Floating-Point Format Specifier - %f

To handle floating-point numbers, you can use %f. Other related specifiers include %e and %E for scientific notation.

// C Program Example#include int main() {float a = 12.67;printf("Using %%f: %f\n", a);return 0;}
