Write a recursive C program to multiple two 3×3 matrices. #include <stdio.h> void multiply(int, int, int [][10], int, int, int [][10], int [][10]); void display(int, int, int[][10]); int main() { int a[10][10], b[10][10], c[10][10] = {0}; int m1, n1, m2, n2, i, j, k; printf("Enter rows and columns for Matrix A respectively: "); scanf("%d%d", &m1,

Write a program to insert an element (given by the user) into an array in a particular position(given by the user). #include <stdio.h> int main() { int i, n, val, a[100],pos; printf("Enter number of elementsn"); scanf("%d",&n); printf("Enter %d integersn", n); for (i = 0; i < n; i++) { printf("n Enter a number: "); scanf("%d",&a[i]);

Write a program to find the transpose of a matrix. #include<stdio.h> int main() { int a[3][3],i,j,val,row,col,k; for(i=0;i<3;i++) { for(j=0;j<3;j++) { printf("n Enter a number: "); scanf("%d",&a[i][j]); } } for(i=0;i<3;i++) { printf("n"); for(j=0;j<3;j++) { printf("%dt",a[i][j]); } } printf("n Transpose Matrix: "); for(i=0;i<3;i++) { printf("n"); for(j=0;j<3;j++) { printf("%dt",a[j][i]); } } return 0; } Join Our Telegram Group

Write a C program which will take input in a 2D array and then take one integer as input and search it is available or not, if it is available display the row and column of the integer. #include<stdio.h> int main() { int a[3][3],i,j,val,row,col,k; for(i=0;i<3;i++) { for(j=0;j<3;j++) { printf("n Enter a number: "); scanf("%d",&a[i][j]); }

Write a program to create an array of n elements and then print maximum and minimum elements from that array. #include<stdio.h> int main() { int i,max,min,a[10]; for(i=0;i<10;i++) { printf("n Enter a Number: "); scanf("%d",&a[i]); } for(i=0;i<10;i++) { printf("n%d",a[i]); } max=min=a[0]; for(i=0;i<10;i++) { if(a[i]>max) max=a[i]; if(a[i]<min) min=a[i]; } printf("n %d is max",max); printf("n %d is min",min);

Write a C program to find the average of n numbers. #include<stdio.h> int main() { int num,i,count,sum=0; printf("n How many nos. you want tio add? "); scanf("%d",&count); for(i=0;i<count;i++) { printf("n Enter a Number: "); scanf("%d",&num); sum=sum+num; } printf("n Aveage= %.2f", (float)sum/(float)count); return 0; } Join Our Telegram Group Visit our Facebook Page Coding Questions Coding

Write a program in C which prints the smallest divisor of an integer , for example smallest divisor of 77 is 7. #include<stdio.h> int main() { int num,i; printf("n Enter the number: "); scanf("%d",&num); for(i=2;i<=num;i++) { if(num%i==0) { printf("n %d is the smallest divisor of %d",i,num); break; } } return 0; } Join Our Telegram

Write a function to sort the characters of the string passed to it as argument. #include<stdio.h> int main() { char c[100],ch; int i,j; printf("n Enter the String: "); gets(c); for(i=0;c[i]!=”;i++) { for(j=i+1;c[j]!=”;j++) { if(c[i]>c[j]) { ch=c[i]; c[i]=c[j]; c[j]=ch; } } } printf("n"); puts(c); return 0; } Join Our Telegram Group Visit our Facebook Page Coding

Write two C programs that calculates factorial of a number using recursion and iteration. #include<stdio.h> int fact(int i) { if(i==0) return 1; if(i==1) return 1; return (i*fact(i-1)); } int main() { int i; printf("n Enter a number: "); scanf("%d",&i); printf("nFactorial of %d = %d ", i, fact(i)); return 0; } Join Our Telegram Group Visit
