Them vao cuoi mang (2 cach)

Code:: /*Them vao cuoi mang*/ #include<stdio.h> main() { int a[100],n=0,m,i; printf("Nhap so phan tu can them: "); scanf("%d",&m); for(i=n;i<(n+m);i++) { printf("a[%d]=",i); scanf("%d",&a[i]); } n+=m; for(i=0;i<n;i++) printf("%-10d",a[i]); printf("\n\nNhap so phan tu can them: ");\\tu day de nhap them lan 2... scanf("%d",&m); for(i=n;i<(n+m);i++) { printf("a[%d]=",i); scanf("%d",&a[i]); } n+=m; for(i=0;i<n;i++) printf("%-10d",a[i]); fflush(stdin); getch(); }

Code:: /*Them vao cuoi mang cach 2*/ #include<stdio.h> main() { int a[100],n=0,m,i; printf("Nhap so phan tu can them: "); scanf("%d",&m); for(i=0;i<m;i++) { printf("a[%d]=",n); scanf("%d",&a[n]); n++; } for(i=0;i<n;i++) printf("%-10d",a[i]); fflush(stdin); getch(); }

Them phan tu vao vi tri bat ky:

Code:: /*Them 1 phan tu vao 1 diem bat ky*/ #include<stdio.h> main() { int a[100]={1,2,3,4,5,6}; int i,n=5,k=3;//k la vi tri cua mang for(i=n;i>k;i--) { a[i]=a[i-1]; } a[k]=4; a[k]=a[i-1]; n++; for(i=0;i<n;i++) printf("%-10d",a[i]); fflush(stdin); getch(); }

Thay the, xoa:

Code:: /*Thay the, xoa, sua 1 phan tu trong mang*/ #include<stdio.h> main() { int a[100]={1,2,3,4,5,6}; int i,n=6,k=2; //k la vi tri can sua(bt k la gia tri phai tim) for(i=k;i<n-1;i++) { a[i]=a[i+1]; } n--; for(i=0;i<n;i++) printf("%-10d",a[i]); fflush(stdin); getch(); }
