1、P18 (1) #include int main(void) int celsius,fahr; fahr=150; celsius=5*fahr/ 9-5*32 /9; printf(fahr=%d,celsius=%dn,fahr,celsius); return 0; (2) #include int main(void) int celsius,fahr; celsius=26; fahr=9*celsius/ 5+32; printf(celsius=%d,fahr=%dn,celsius,fahr); return 0; (3) #include int main(void) i

2、nt average,math,eng,comp; math=87; eng=72; comp=93; average=(math+eng+comp)/ 3; printf(math=%d,eng=%d,comp=%d,average=%dn,math,eng,comp,average); return 0; (4) #include int main(void) int n,a,b,c; n=152; c=n%10; b=(n/10)%10; a=n/100; printf(”整数d的个位数字就是 d,十位数字就是 d，百位数字就是 dn,n,c,b,a); return 0; P27 (1

3、) #include #include int main(void) int celsius,fahr; printf(Enter celsius:); scanf(%d, fahr=9*celsius/ 5+32; printf(fahr%dn,fahr); return 0; (2) #include #include int main(void) int money,year; double rate,interest; printf(Enter money,year,rate:); scanf(%d%d%lf, interest=money*pow(1+rate,year)-money

4、; printf(interest=% 、2fn,interest); return 0; (3) #include #include int main(void) double x,y; printf(Enter x:); scanf(%lf, if(x0) y=pow(x+1,2)+2*x+1 /x; else y=sqrt(x); printf(y=f(%f)=% 、 2fn,x,y); return 0; (4) #include int main(void) int x,y; printf(Enter num1:); scanf(%d, printf(Enter num2:); scanf(%d, printf(%d+%d=%dn,x,y,x+y); printf(%d-%d=%dn,x,y,x-y); printf(%d*%d=%dn,x,y,x*y); printf(%d/%d=%dn,x,y,x/y); printf(%d%d=%dn,x,y,x%y); return 0; 10 的阶乘 #include int main(void) int i,n,product; printf(Enter n:); scanf(%d, product=1
