编写一个C程序，演示指针的示例

#include void main(){ //Declaring variables and pointer// int a=2; int *p; //Declaring relation between variable and pointer// p=&a; //Printing required example statements// printf("Size of the integer is %d

",a,p);//Address value// printf("Value of %d is %d

",a,*p);//2// printf("Value of next address location of %d is %d

",a,*(p+1));//Garbage value from (p+1) address// printf("Address of next address location of %d is %d

",a,(p+1));//Address value +4// //Typecasting the pointer// //Initializing and declaring character data type// //a=2 = 00000000 00000000 00000000 00000010// char *p0; p0=(char*)p; //Printing required statements// printf("Size of the character is %d

",sizeof(char));//1// printf("Address of %d is %d

",a,p0);//Address Value(p)// printf("Value of %d is %d

",a,*p0);//First byte of value a - 2// printf("Value of next address location of %d is %d

",a,*(p0+1));//Second byte of value a - 0// printf("Address of next address location of %d is %d

",a,(p0+1));//Address value(p)+1// }
