An array is a group of related data items that are stored with single name.
For example, int student[30]; //student is an array name that holds 30 collection of data items with a single variable name
Operations of array
Searching − It is used to find whether particular element is present or not
Sorting − It helps in arranging the elements in an array either in ascending or descending order.
Traversing − It processes every element in an array sequentially.
Inserting − It helps in inserting the elements in an array.
Deleting − It helps in deleting an element in an array.
The logic applied to perform arithmetic operation of two-dimensional array is as follows −
for(row = 0; row < i; row++){
for(col = 0;col < j;col++){
add[row][col] = A[row][col] + B[row][col];
sub[row][col] = A[row][col] - B[row][col];
mul[row][col] = A[row][col] * B[row][col];
div[row][col] = A[row][col] / B[row][col];
mod[row][col] = A[row][col] % B[row][col];
}
}The logic applied to print all arithmetic operation of two-dimensional array is as follows −
printf("\nAdd\t Sub\t Mul\t Div\t Mod\n");
printf("-------------------------------\n");
for(row = 0; row < i; row++){
for(col = 0; col < j; col++){
printf("\n%d \t ", add[row][col]);
printf("%d \t ", sub[row][col]);
printf("%d \t ", mul[row][col]);
printf("%.2f \t ", div[row][col]);
printf("%d \t ", mod[row][col]);
}
}Program
Following is the C program to perform arithmetic operations on two-dimensional array −
#include<stdio.h>
int main(){
int i, j, row, col,A[20][20], B[20][20];
int add[10][10], sub[10][10], mul[10][10], mod[10][10];
float div[10][10];
printf("enter no: of rows and columns:\n");
scanf("%d %d", &i, &j);
printf("enter elements of 1st array:\n");
for(row= 0; row < i; row++){
for(col = 0;col < j;col++){
scanf("%d", &A[row][col]);
}
}
printf("enter elements of 2nd array:\n");
for(row = 0; row < i; row++){
for(col = 0;col < j;col++){
scanf("%d", &B[row][col]);
}
}
for(row = 0; row < i; row++){
for(col = 0;col < j;col++){
add[row][col] = A[row][col] + B[row][col];
sub[row][col] = A[row][col] - B[row][col];
mul[row][col] = A[row][col] * B[row][col];
div[row][col] = A[row][col] / B[row][col];
mod[row][col] = A[row][col] % B[row][col];
}
}
printf("\nAdd\t Sub\t Mul\t Div\t Mod\n");
printf("-------------------------------\n");
for(row = 0; row < i; row++){
for(col = 0; col < j; col++){
printf("\n%d \t ", add[row][col]);
printf("%d \t ", sub[row][col]);
printf("%d \t ", mul[row][col]);
printf("%.2f \t ", div[row][col]);
printf("%d \t ", mod[row][col]);
}
}
return 0;
}Output
When the above program is executed, it produces the following result −
enter no: of rows and columns: 3 4 enter elements of 1st array: 1 2 4 5 6 7 3 8 3 2 1 8 enter elements of 2nd array: 1 2 1 2 1 3 4 2 1 2 1 1 Add Sub Mul Div Mod ------------------------------- 2 0 1 1.00 0 4 0 4 1.00 0 5 3 4 4.00 0 7 3 10 2.00 1 7 5 6 6.00 0 10 4 21 2.00 1 7 -1 12 0.00 3 10 6 16 4.00 0 4 2 3 3.00 0 4 0 4 1.00 0 2 0 1 1.00 0 9 7 8 8.00 0
