給定一個矩陣,我們需要列印矩陣的邊界元素並顯示它們的總和。
參考下面給出的矩陣-
1 2 3 4 5 6 7 8 9
1 2 3 4 6 7 8 9
邊界元素總和: 1 2 3 4 6 7 8 9 = 40
求邊界矩陣之和的邏輯如下如下-
for(i = 0; i<m; i++){ for(j = 0; j<n; j++){ if (i == 0 || j == 0 || i == n – 1 || j == n – 1){ printf("%d ", mat[i][j]); sum = sum + mat[i][j]; } else printf(" "); } printf("</p><p>"); }
#以下是用於列印矩陣邊界元素總和的C程式-
#include<stdio.h> #include<limits.h> int main(){ int m, n, sum = 0; printf("</p><p>Enter the order of the matrix : "); scanf("%d %d",&m,&n); int i, j; int mat[m][n]; printf("</p><p>Input the matrix elements</p><p>"); for(i = 0; i<m; i++){ for(j = 0; j<n; j++) scanf("%d",&mat[i][j]); } printf("</p><p>Boundary Matrix</p><p>"); for(i = 0; i<m; i++){ for(j = 0; j<n; j++){ if (i == 0 || j == 0 || i == n – 1 || j == n – 1){ printf("%d ", mat[i][j]); sum = sum + mat[i][j]; } else printf(" "); } printf("</p><p>"); } printf("</p><p>Sum of boundary is %d", sum); }
當執行上述程式時,會產生下列結果-
Enter the order of the matrix : 3 3 Input the matrix elements : 1 2 3 4 5 6 7 8 9 Boundary Matrix : 1 2 3 4 6 7 8 9 Sum of boundary is 40
以上是印出矩陣邊界元素總和的C程序的詳細內容。更多資訊請關注PHP中文網其他相關文章!
