    printf("x = %d\t", --x); 
    printf("x = %d\n", x);
    return 0;
  }
  

Output

x = 8  x = 9  x = 8  x = 8
  

Steps Description

• Declare integer variable x = 8
• Initialize in integer variable x = 8
• printf inbuild function to display value of variable x in decimal place holder %d = x for formatting tab separate or \t is used
• printf inbuild function to display prefix increment value variable x in decimal place holder %d = 9 for formatting tab separate or \t is used
• printf inbuild function to display variable x in decimal place holder %d = 9 for formatting tab separate or \t is used
• printf inbuild function to display prefix decrement x in decimal place holder %d x = 8 for formatting tab separate or \t is used
• printf inbuild function to display variable x in decimal place holder %d x = 8 for formatting tab separate or \t is used
