1.      Write a program that prints the following text at the terminal.

· In C, lowercase letters are significant.

· main is where program execution begins.

· Opening and closing braces enclose program statements in a routine.

· All program statements must be terminated by a semicolon.

 

#include <stdio.h>

 

int main() {

   

    printf("In C, lowercase letters are significant.\n");

    printf("main is where program execution begins.\n");

    printf("Opening and closing braces enclose program statements in a routine.\n");

    printf("All program statements must be terminated by a semicolon.\n");

    return 0;

}

4.      What output would you expect from the following program?

#include <stdio.h>

int main (void) {

printf ("Testing...");

printf ("....1");

printf ("...2");

printf ("..3");

printf ("\n");

return 0;

}

Testing.......1...2..3
