Am asked about how to store the dates in array while running time, read data from an array
in c we have
for ( i = 0 ; i <= 29 ; i++ ) { printf ( "\nEnter marks " ) ; scanf ( "%d", &marks[i] ) ; /* store data in array / } for ( i = 0 ; i <= 29 ; i++ ) sum = sum + marks[i] ; / read data from an array*/
avg = sum / 30 ; printf ( "\nAverage marks = %d", avg ) ; }
it means my question is this are my elements 1 8 9 12 15 .and now how write and read in arrays
