河工大C语言课程第二版甘勇课本第四章课后题答案PPT展示.ppt

1、本次PPT制作了C语言程序设计（第二版）甘勇主编的第四章课后习题的答案程序详细代码。,课后习题118全部答案,(1) 输入学生成绩，输出不及格率,#include #include int main(void) int n,i,l; double x,fail,sum,average; sum=0,l=0; printf(place input students amount:); scanf(%d, ,(2) 输入n个整数，输出其中负数，0，整数的个数,#include #include int main(void) int n,i,j,k,l; j=0,k=0,l=0; printf(pl

2、ace input digits amount:); scanf(%d, ,(3) 输入n个整数，输出绝对值最小数,#include #include int main(void) int n,x,min,i; int x1,x2; printf(place input digits amount:); scanf(%d, ,(4)输入一个数n，输出1-n的所有是7或者11的倍数，但不同时是7和11的倍数,#include #include int main(void) int n,i; printf(place input a digit:); scanf(%d, ,(5) 数列：1-1/4

3、+1/7-1/10+1/13-.求和；,#include #include int main(void) int i,n; double sum=0,x=1.0; printf(place input series summation amount:); scanf(%d, ,(6) 数列:1-2/3+3/5-4/7+5/9-.求和；,#include #include int main(void) int i,n; double sum=0,x,y; printf(place input series summation amount:); scanf(%d, ,(7) 计算 sin(x)

4、前20项；,#include #include int main(void) int i,j,a; double sum=0,x1,y1,x,y; printf(place input a digit:); scanf(%lf, ,(8) 1!+2!+3!+.n! (n=20),#include #include int main(void) int i,sum=0,n,j,y; printf(place input max digit:); scanf(%d, ,(9) 1!+2!+3!+.+m!n, input a digit n, m belong (?,?).,#include #in

5、clude int main(void) int i,sum=0,j,y,n,m; printf(place input max digit:); scanf(%d, ,(10) 学生成绩等级；,#include #include int main(void) int i,n; double score,max; printf(place input students amount:); scanf(%d, ,(11) *,#include #include int main(void) int n,a; printf(place a digit:); scanf(%d, ,(12) 最大公约

6、数*,#include #include int main(void) int a,b; int r; printf(place input a:); scanf(%d, ,(13) *,#include #include int main(void) int a,b,n,m; int r; printf(place input a:); scanf(%d, ,(14) *,#include #include int main(void) int i,a,n; int s=0; printf(place a digit(=9):); scanf(%d, ,(15) * *,#include #

7、include int main(void) int m,n,a,b,c,x; printf(*input double digits all a three digit*n); printf(place a min digit:); scanf(%d, ,(16) *,#include #include int main(void) int sum1,sum2,x,y,z; for(x=0;x=9;x+) for(y=0;y=9;y+) for(z=0;z=9;z+) sum1=x*100+y*10+z; sum2=y*100+z*10+z; if(sum1+sum2=532) printf(%d %d %dn,x,y,z); return 0; ,(17) *,#include #include int main(void) int i,T,j; int x; printf(place input test amount:); scanf(%d, ,(18) *,#incl
