C语言课程设计实验报告第一题：编程思路：源程序：#includevoid main() int i,k,s; for(i=0;i=8;i+) for(k=0;k=i;k+) s=(i+1)*(k+1); printf(%7d,s); printf(n); getch(); 执行结果： 1 2 4 3 6 9 4 8 12 16 5 10 15 20 25 6 12 18 24 30 36 7 14 21 28 35 42 49 8 16 24 32 40 48 56 64 9 18 27 36 45 54 63 72 81第二题：编程思路：源程序：#include#includevoid main() int x,i=1,m=1,n=0; randomize(); x=random(100)+1; printf(Please guess the number:n); while(i=1) scanf(%d,&m); n+; if(mx) printf(HIGHn); else if(mx) printf(LOWn); else i=0; if(n7&n15) printf(I bet you can do it better.n); else exit(0); getch(); 执行结果：Please guess the number:34_LOW45_LOW78_HIGH67_LOW70_LOW75_LOW77_HIGH76_I beg you can do it better!第三题：编程思路：源程序：#includevoid main() int a17=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17; int i,m=0,n=16; printf(array a:n); for(i=0;i17;i+) ai=i+1;i=0; for(i=0;i0) if(ai0)m=m+1; if(m=3) printf( %d,i+1); ai=0; n=n-1; m=0; i+; if(i=17) i=0; printf(n); getch(); 执行结果：array a:3 6 9 12 15 1 5 10 14 28 16 7 17 13 4第四题：编程思路：源程序：#includevoid main() long int paixu (long int n1); long int n,r; r=paixu(n); printf(%ldn,r); getch(); long int paixu (long int n1) long int r1; long int g,s,b,q,w,t; printf(Please input the number:n); scanf(%ld,&n1); w=n1/10000; q=(n1-10000*w)/1000; b=(n1-10000*w-1000*q)/100; s=(n1-10000*w-1000*q-100*b)/10; g=n1-10000*w-1000*q-100*b-10*s; printf(%ld %ld %ld %ld %ldn,w,q,b,s,g); if(wq) t=w; w=q； q=t; if(wb) t=w; w=b; b=t; if(ws) t=w; w=s; s=t; if(wg) t=w; w=g; g=t; if(qb) t=q; q=b; b=t; if(qs) t=q; q=s; s=t; if(qg) t=q; q=g; g=t; if(bs) t=b; b=s; s=t; if(bg) t=b; b=g; g=t; if(sg) t=s; s=g; g=t; printf(%ld %ld %ld %ld %ldn,w,q,b,s,g); r1=10000*w+1000*q+100*b+10*s+g; return(r1);执行结果：Please input the number:23094_2 3 0 9 49 4 3 2 094320第五题：编程思路源程序：#includevoid main() int p,e,a,r; for(p=0;p=9;p+) for(e=0;e=9;e+)if(e!=p) for(a=0;a=9;a+) if(a!=p&a!=e) for(r=0;r=9;r+) if(r!=p&r!=e&r!=a&p*1000+e*100+a*10+r-(a*100+r*10+a)= p*100+e*10+a) printf(%d %d %d %dn,p,e,a,r); getch();执行结果：1 0 9 8第六题：编程思路：源程序：#includevoid main() int a8080,n; int i1,i2,j1,j2,i,j,sj=0; printf(Please input n:n); scanf(%d,&n); i1=0;i2=n-1; j1=0;j2=n-1; while(sjn*n) for(i=i1;i=i2;i+) sj+; aij1=sj; j1+;for(j=j1;j=i1;i-) sj+; aij2=sj; j2-;for(j=j2;j=j1;j-) sj+; ai1j=sj; i1+; for(i=0;in;i+) for(j=0;jn;j+) printf(%4d ,aij); printf(n); getch(); 执行结果：Please input n:7_1 24 23 22 21 20 192 25 40 39 38 37 183 26 41 48 47 36 174 27 42 49 46 35 165 28 43 44 45 34 156 29 30 31 32 33 14 7 8 9 10 11 12 13 第七题：编程思路：源程序：#includevoid main() long int a20; int i; a0=1;a1=1; for(i=2;i20;i+) ai=ai-2+2*ai-1; for(i=0;i20;i+) if(i%5=0) printf(n); printf(%12ld,ai); printf(n); getch();执行结果： 1 1 3 7 1741 99 239 577 1393 3363 8119 19601 47321 114243 275807 865857 1607521 3880899 9369319第八题：编程思路：源程序：#includevoid main() int *p,i,t; int a10=1,3,4,5,6,8,10,14,20,21; printf(Please input the number:n); scanf(%d,p); printf(Please input the shulie:n); for(i=0;i10;i+) printf(%d ,ai); for(i=0;i*p) t=ai;ai=*p;*p=t; printf(nThe new shulie is %d %d %d %d %d %d %d %d %d %d %dn,a0,a1,a2
