1套 每一套题目都是按照“填空题--改错题编程题”顺序排列,填空题上面带有两 个划线的是人工做题时候多余划线，不要理睬！！ #include stdlib.h #include stdio.h #define N 10 double fun(double *x) { int i, j; double av, y[N]; av 0; /**********found**********/ for(i 0; iN; i++) av + x[i]/N for(i j 0; iN; i++) if(x[i]av ){ /**********found**********/ y[j] x[i]; x[i] -1;__j++__;} i 0; while(iN) { if(x[i]! -1 ) y[j++] x[i]; /**********found**********/ __i++__; } for(i 0; iN; i++)x[i] y[i]; return av; } main() { int i; double x[N]; for(i 0; iN; i++){x[i] rand()%50;printf(%4.0f ,x[i]);} printf(\n); printf(\nThe average is:%f\n,fun(x)); printf(\nThe result :\n,fun(x)); for(i 0; iN; i++) printf(%5.0f ,x[i]); printf(\n); } 改错题 1 #include stdio.h void fun ( char *s, int num[5] ) { int k, i 5; for (k 0;ki;k++ ) /**********found**********/ num[k] 0; for (; *s; s++) { i -1; /**********found**********/ switch (* s ) { case a: case A: {i 0; break;} case e: case E: {i 1; break;} case i: case I: {i 2; break;} case o: case O: {i 3; break;} case u: case U: {i 4; break;} } if (i 0) num[i]++; } } main() { char s1[81]; int num1[5], i; printf( \nPlease enter a string: ); gets( s1 ); fun ( s1, num1 ); for ( i 0; i 5; i++ ) printf (%d ,num1[i]);printf (\n); } 编程题 #include stdio.h 2 #define M 4 #define N 5 int fun ( int a[M][N] ) { int tot 0,i,j; for(i 0;iN;i++) { tot+ a[0][i]; tot+ a[M-1][i]; } for(i 1;iM-1;i++) { tot+ a[i][0]; tot+ a[i][N-1]; } return tot; } main() { int aa[M][N] {{1,3,5,7,9}, {2,9,9,9,4}, {6,9,9,9,8}, {1,3,5,7,0}}; int i, j, y;void NONO (); printf ( The original data is : \n ); for ( i 0; iM; i++ )
