Implement a function to print the multiplication table, the number of rows and the number of columns of the table itself specified,Input 9, output 9*9 table, output , output 12*12 multiplication table. Program:#include void mul (int n) //multiplication Multiplication{int I, J; for (i = 1; I n; i++){ for (j = 1; J {printf ("%d*%d=%-2d", I, J, i*j);Where 2 in%2d means output two cells, number backward, that is, right-justified;%-2d, the number is left-justified}printf ("\ n");}}int Main (){int

Stores n integers in the array in reverse order. Solution: Program 1:#include int inv (int x[], int n){int temp, I, j, M = (n-1)/2;for (i = 0; I {j = n-1-I;temp = X[i];X[i] = X[j];X[J] = temp;}Return}int main (){int I, a[10] = {1,2,3,4,5,6,7,8,9,10};printf ("The original array:\n");for (i = 0; i {printf ("%d", a[i]);}printf ("\ n");INV (A, 10);printf ("The array has been inverted:\n");//inverted: Reversefor (i = 0; i {printf ("%d", a[i]);}printf ("\ n");return 0;}Program 2: Using pointer variabl

Enter a positive number less than zero from the keyboard , which requires the output of its square root (if the square root is not an integer, output its integer portion). Requires that the data be checked for a positive number that is less than zero after it is entered . If not, a re-entry is required. Solution: Program:#include #include #define M 1000int main (){int x, y;printf ("Please enter a positive number less than%d x:", M);scanf ("%d", x);while (X>M){printf ("Input data does not meet

input data with scanf, the output of the calculation results require a text description, take the decimal point after 2 digits. the circumference length, circle area, sphere surface area, sphere volume and cylinder volume are obtained. Program:#include int main (){float H,r,c,s,sq,vq,vz;float pi = 3.141526;printf ("Please input circle radius r, Cylinder high H:");scanf ("%f,%f", r,h);c = 2 * PI*R;s = pi*r*r;Sq = 4 * PI*R*R;VQ = (4/3) *pi*r*r*r;VZ = pi*r*r*h;printf ("Circumferential Length: c=%6.

Use the nested invocation of a function to find the largest number in 4 integers. (recursive)Solution: Program:#include int max2 (int a,int b){Return (a > B? a:b);}int max4 (int a, int b,int c,int D){int max2 (int a, int b);Return Max2 (Max2 (Max2 (A, B), c), D);}int main (){int A, b, C,d,max;printf ("Please enter four integer numbers:");scanf ("%d,%d,%d,%d", a, b,c,d);max = Max4 (A, b,c,d);printf ("Max is%d\n", Max);return 0;}Results:Please enter four integer numbers:-1,2,45,2Max is 45Please p

There is a 3*4 matrix that requires the program to find the value of the largest element in it, along with its line number and column number. (Daleitai algorithm)Solution: Program:#include int main (){int I, j, row = 0, Colum = 0, Max;int A[3][4] = {{1,2,3,4},{4,5,6,7},{-1,3,-5,10}};max = a[0][0];printf ("Array a:\n");for (i = 0; I {for (j = 0; J {printf ("%5d", A[i][j]);}printf ("\ n");}for (i = 0; I {for (j = 0; J {if (A[i][j] > Max){max = A[i][j];row = i;Colum = j;}}}printf ("max=%d\nrow=%d\n
