Printf() function in c programming

• In C programming language, printf() function is used to print the (“character, string, float, integer, octal and hexadecimal values”) onto the output screen.
• We use printf() function with %d format Specifier to display the value of an integer variable.
• Similarly %c is used to display character, %f for float variable, %s for string variable, %lf for double and %x for hexadecimal variable.
• To generate a newline, we use “\\n” in C printf() statement.

For Example:-

#include <stdio.h>


int main()
char ch = ‘A’;
char str[20] = “”;
float flt = 10.234;
int no = 150;
double dbl = 20.123456;
printf(“Character is %c \\n”, ch);
printf(“String is %s \\n” , str);
printf(“Float value is %f \\n”, flt);
printf(“Integer value is %d\\n” , no);
printf(“Double value is %lf \\n”, dbl);
printf(“Octal value is %o \\n”, no);
printf(“Hexadecimal value is %x \\n”, no);
return 0;
