Write a c program to copy a data of file to other file.

Correct Answer: #include int main() { int a[5][5], b[5][5], c[5][5], i, j, k, sum = 0, m, n, o, p; printf( "\nEnter the row and column of first matrix" ); scanf( "%d %d", &m, &n ); printf( "\nEnter the row and column of second matrix" ); scanf( "%d %d", &o, &p ); if(n!=o) { printf( "Matrix mutiplication is not possible" ); printf( "\nColumn of first matrix must be same as row of second matrix" ); } else { printf( "\nEnter the First matrix" ); for( i=0; i

Correct Answer: #include int main(){ int a[10],i,n,m,c=0,l,u,mid; printf("Enter the size of an array: "); scanf("%d",&n); printf("Enter the elements in ascending order: "); for(i=0;i

Correct Answer: #include #define MAX 50 void mergeSort(int arr[],int low,int mid,int high); void partition(int arr[],int low,int high); int main(){ int merge[MAX],i,n; printf("Enter the total number of elements: "); scanf("%d",&n); printf("Enter the elements which to be sort: "); for(i=0;imid){ for(k=m;k<=high;k++){ temp[i]=arr[k]; i++; } } else{ for(k=l;k<=mid;k++){ temp[i]=arr[k]; i++; } } for(k=low;k<=high;k++){ arr[k]=temp[k]; } } Sample output: Enter the total number of elements: 5 Enter the elements which to be sort: 2 5 0 9 1 After merge sorting elements are: 0 1 2 5 9

Correct Answer: #include int main(){ int i,j,s,temp,a[20]; printf("Enter total elements: "); scanf("%d",&s); printf("Enter %d elements: ",s); for(i=0;i=0)){ a[j+1]=a[j]; j=j-1; } a[j+1]=temp; } printf("After sorting: "); for(i=0;i

Correct Answer: #include void quicksort(int [10],int,int); int main(){ int x[20],size,i; printf("Enter size of the array: "); scanf("%d",&size); printf("Enter %d elements: ",size); for(i=0;ix[pivot]) j--; if(i

Correct Answer: Output: 2 p q 1400000

Correct Answer: hi

Correct Answer: 5

Correct Answer: extern int i is a declaration and not a definition, hence Error occured

Correct Answer: There is no difference except for the fact that the first one gives a hint that the function fun() is probably in another source file
