Answer:
Input example:
select the funcion: 1
write the 1sd number2
write the 2nd number1
value is 2.000000
Explanation:
#include <stdio.h>
main()
{
//define the variables as float
float a, b, c, e;
char d;
while (1)
{
//input values
printf("select the function: ");
scanf("%c",&d);
printf("write the 1sd number");
scanf("%f",&a);
getchar();
printf("write the 2nd number");
scanf("%f",&b);
getchar();
if (d=='%')
{
a=a*b/100;
}
if (d=='*')
{
a=a*b;
}
if (d=='+')
{
a=a+b;
}
if (d=='/')
{
a=a/b;
}
if (d=='-')
{
a=a-b;
}
printf("value is %f \n",a);
}
printf("final value is %f",a);
getchar();
}
Answer:
Microsoft Windows - More susceptible to viruses
Linux - Limited support system
Apple - Fewer compatible applications

Answer:
2. Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano.
Explanation:
The options are:
1. Before a volcano erupts, earthquake activity beneath the volcano decreases.2. Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano.3. When a volcano erupts, the amount of carbon dioxide and sulfur dioxide emitted decreases. 4.Scientists measure the amount of these gases to determine the amount of magma present in the volcanic reservoir.
The answer is certainly 2. as seismometers are being used to find out the details of the earthquake activities which occur inside a volcano. And with this information, the volcanologists then predict the eruption of that particular volcano. Hence, the 2nd option does not have any factual errors, and all the others have factual errors.
