#include

void main()

{

printf("These values are:\n");

float x=2.5,y=2.5,z=2.5;

printf("x=%f\n",x);

printf("y=%f\n",y);

printf("z=%f\n",z);

}

例3.1

#include

main()

{

int x = 153, b0, b1, b2, sum;

b2 = x / 100;

b1 = (x - b2 * 100) / 10;

b0 = x % 10;

sum = b2 + b1 + b0;

printf("b2=%d, b1=%d, b0=%d, sum=%d\n", b2, b1, b0, sum); }
