Correct Answer: #include int main(){ int num,i,f,r,sum=0,temp; printf("Enter a number: "); scanf("%d",&num); temp=num; while(num){ i=1,f=1; r=num%10; while(i<=r){ f=f*i; i++; } sum=sum+f; num=num/10; } if(sum==temp) printf("%d is a strong number",temp); else printf("%d is not a strong number",temp); return 0; } Sample output: Enter a number: 145 145 is a strong number

Correct Answer: #include int main(){ int r,i,j,k; printf("Enter the number range: "); scanf("%d",&r); for(i=1;i<=r;i++){ for(j=1;j<=10;j++) printf("%d*%d=%d ",i,j,i*j); printf("\n"); } return 0; } Sample Output: Enter the number range: 5 1*1=1 1*2=2 1*3=3 1*4=4 1*5=5 1*6=6 1*7=7 1*8=8 1*9=9 1*10=10 2*1=2 2*2=4 2*3=6 2*4=8 2*5=10 2*6=12 2*7=14 2*8=16 2*9=18 2*10=20 3*1=3 3*2=6 3*3=9 3*4=12 3*5=15 3*6=18 3*7=21 3*8=24 3*9=27 3*10=30 4*1=4 4*2=8 4*3=12 4*4=16 4*5=20 4*6=24 4*7=28 4*8=32 4*9=36 4*10=40 5*1=5 5*2=10 5*3=15 5*4=20 5*5=25 5*6=30 5*7=35 5*8=40 5*9=45 5*10=50

Correct Answer: include int main(){ int s,i,j,temp,a[20]; printf("Enter total elements: "); scanf("%d",&s); printf("Enter %d elements: ",s); for(i=0;ia[j]){ temp=a[i]; a[i]=a[j]; a[j]=temp; } } } printf("After sorting is: "); 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: #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 #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 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 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(){ FILE *p,*q; char file1[20],file2[20]; char ch; printf("\nEnter the source file name to be copied:"); gets(file1); p=fopen(file1,"r"); if(p==NULL){ printf("cannot open %s",file1); exit(0); } printf("\nEnter the destination file name:"); gets(file2); q=fopen(file2,"w"); if(q==NULL){ printf("cannot open %s",file2); exit(0); } while((ch=getc(p))!=EOF) putc(ch,q); printf("\nCOMPLETED"); fclose(p); fclose(q); return 0; }

Correct Answer: Output: 2 p q 1400000
