Prefix Increment Decrement

Program to use Prefix Increment Decrement in C Language

#include<stdio.h>
  int main()
  {
    int a = 6;
    printf("a = %d\t",a);
    printf("a = %d\t",++a);
    printf("a = %d\t",a);
    printf("a = %d\t",--a);
    printf("a = %d\n",a);
    return 0;
  }
  

Output

a = 6     a = 7     a = 7     a = 6     a = 6
  

Steps Description

• Declare integer variable a = 6
• Initialize in integer variable a = 6
• printf inbuild function to display value of variable a in decimal placeholder %d a = 6 for formatting tab separator \t is used
• printf inbuild function to display prefix increment values variable a in decimal placeholder %d a = 7 for formatting tab separator \t is used
• printf inbuild function to display value of variable a in decimal placeholder %d a = 7 for formatting tab separator \t is used
• printf inbuild function to display prefix decrement values variable a in decimal placeholder %d a = 6 for formatting tab separator \t is used
• printf inbuild function to display value of variable a in decimal placeholder %d a = 6 for formatting tab separator \t is used
