C program using one dimensional array

For example; an int array store the elements of int data type and a float array holds the elements of float data type, so on. You can use the following syntax to declare an array in the c programming language; as shown below:. To initialize an array in c by using the index of each element. See the following easy way to initialize array in c programming; as shown below:.

Using array index, you can easily access any element stored in c array; as shown below:. Let, you have declared an array named mark as above. So, you can access the element values in array by using array index; as shown below:. Use the following steps to write program to print largest and second largest element of the array in c:. My name is Devendra Dode. But for arrays the following statement is wrong.

We must copy between arrays element by element and the two arrays must have the same size. I hope you enjoy this article. I would like to have your feedback.

The second for loop prints all the elements of an array one by one.

How it works: The first for loop asks the user to enter five elements into the array. The second for loop reads all the elements of an array one by one and accumulate the sum of all the elements in the variable s. Note that it is necessary to initialize the variable s to 0 , otherwise, we will get the wrong answer because of the garbage value of s. When an array is declared inside a function the elements of the array have garbage value. If an array is global or static, then its elements are automatically initialized to 0.

We can explicitly initialize elements of an array at the time of declaration using the following syntax:. While initializing 1-D array it is optional to specify the size of the array, so you can also write the above statements as:.

If the number of initializers is less than the specified size then the remaining elements of the array are assigned a value of 0. After this initialization the elements of the array are as follows:.

If the number of initializers is greater than the size of the array then the old compilers will report an error. However, most new compilers simply issue a warning message. How it works: In line 6, first, we have declared and initialized an array of 10 integers.

In the next line, we have declared three more variables of type int namely: i , max and min. A for loop is used to iterate through all the elements of an array. The second if statement checks whether the value of the current element is smaller than the value of min. If it is, we assign the value of the current element to min.

This process continues until there are elements in the array left to iterate. When the process is finished, max and min variables will have maximum and minimum values respectively.
