  Objective The fundamental data types in c are int, float, and char. Today, we're discussing int and float data types. The  printf()  function prints the given statement to the console. The syntax is  printf("format string",argument_list); . In the function, if we are using an integer, character, string, or float as an argument, then in the format string we have to write  %d  (integer),  %c  (character),  %s  (string),  %f  (float) respectively. The  scanf()  the function reads the input data from the console. The syntax is  scanf("format string",argument_list); . For ex: The  scanf("%d",&number)  the statement reads an integer number from the console and stores the given value in a variable  . To input two integers separated by a space on a single line, the command is  scanf("%d %d", &n, &m) , where   and   are the two integers.
