The document contains code for a C program that uses the sizeof operator to print the sizes of various data types including int, char, float, and double. The program defines a main function containing an integer variable x. It then uses sizeof and printf statements to output the sizes of x, char, int, short, long, float, and double.

3. #include<stdio.h>
int main(void)
{
int x;
printf(" x : %dn", sizeof(x));
printf("char : %dn", sizeof(char));
printf("int : %dn", sizeof(int));
printf("short : %dn", sizeof(short));
printf("long : %dn", sizeof(long));
printf("float : %dn", sizeof(float));
printf("double : %dn", sizeof(double));
return 0;
}

int x;
printf(" x : %dn", sizeof(x));
printf("char : %dn", sizeof(char));
printf("int : %dn", sizeof(int));

printf("long : %dn", sizeof(long));
printf("float : %dn", sizeof(float));
printf("double : %dn", sizeof(double));
