As the name implies, you only need to calculate the sum result:

# include & ltstdlib.h & gt

# include & ltstdio.h & gt

# include & lttime.h & gt

int main()

{

int n= 10，i= 1，count = 0；

srand(time(0))；

for(； I & ltn；; i++)

{

int m；

if((m = rand()% 100+ 1)& amp； 1)= = 0)/* x & amp； 1==0 means it is even */

{

count+= m；

}

}

printf("%d\n "，count)；

getchar()；

}
