ARRANGE THE ELEMENTS IN ARRAY IN DESCENDING ORDER main() { int a[100],i,n,j,search,temp; printf("\n how many no's in array"); scanf("%d",&n); printf("\n enter %d elements in array",n); for(i=0;i scanf("%d",&a[i]); for(i=0;i { for(j=i+1;j { if(a[i] { temp=a[i]; a[i]=a[j]; a[j]=temp; } } printf("%4d",a[i]); } getch(); }

Add two matrices and store the result #include<stdio.h> #include<conio.h> void main() { int a[3][3],b[3][3],c[3][3],i,j; clrscr(); printf("Enter the elements into matrix A\n"); for(i=0;i<3;i++) for(j=0;j<3;j++) scanf("%d",&a[i][j]); printf("\nEnter the elements into matrix B\n"); for(i=0;i<3;i++) for(j=0;j<3;j++) scanf("%d",&b[i][j]); for(i=0;i<3;i++) for(j=0;j<3;j++) c[i][j]=a[i][j]+b[i][j]; for(i=0;i<3;i++) { printf("\t\t"); for(j=0;j<3;j++) printf("%d\t",c[i][j]); printf("\n\a"); } getch(); }

Add numbers using command line arguments (CLA) #include<stdio.h> #include<conio.h> #include<stdlib.h> void main(int argc,char *argv[]) { int sum=0,i; //Compare if proper number of arguments have been entered if(argc<3) { printf("Insufficient number of arguments:\n"); getch(); return 0; } //Add all the numbers entered using atoi function for(i=1;i<argc;i++) { sum+=atoi(argv[i]); } //print the sum printf("Ans=%d",sum); getch(); }
