C Language Examples - Find the Maximum Value
Use the numerical value specified by user input to determine the maximum value.
Example - Find the Maximum Value
#include <stdio.h>
#include <stdlib.h>
int main()
{
int i, num;
float *data;
printf("Enter the number of elements (1 ~ 100):");
scanf("%d", &num);
// Allocate memory for 'num' elements
data = (float*) calloc(num, sizeof(float));
if(data == NULL)
{
printf("Error!!! Memory not allocated.");
exit(0);
}
printf("\n");
// User input
for(i = 0; i < num; ++i)
{
printf("Enter number %d:", i + 1);
scanf("%f", data + i);
}
// Loop to find the maximum value
for(i = 1; i < num; ++i)
{
// If you need to find the minimum value, change < to >
if(*data < *(data + i))
*data = *(data + i);
}
printf("Maximum element = %.2f", *data);
return 0;
}
The output result is:
输入元素个数(1 ~ 100): 5 输入数字 1: 12 输入数字 2: 32 输入数字 3: 6 输入数字 4: 56 输入数字 5: 21 最大元素 = 56.00other extensions
