Find the maximum value among 5 numbers. Hint: ① Define i, max, a[5] as int type, and initialize max=a[0]. ② Input an 5 integer array using scanf() function by loop. ③ Compare max with 5 elements in sequence, and if it is less than one of them, update max. ③ Print max. For example Input: Please enter 5 numbers: 10 6 15 4 8 Output: The maximum value is 15.

Sure, here is the code in C language to find the maximum value among 5 numbers:

#include <stdio.h>

int main() {
    int i, max, a[5];
    
    // input 5 numbers
    printf("Please enter 5 numbers: ");
    for(i=0; i<5; i++) {
        scanf("%d", &a[i]);
    }
    
    // find the maximum value
    max = a[0];
    for(i=1; i<5; i++) {
        if(a[i] > max) {
            max = a[i];
        }
    }
    
    // output the result
    printf("The maximum value is %d.\n", max);
    
    return 0;
}

You can copy and paste this code to a C file, and then compile and run it to see the result. Let me know if you have any other questions.
