Multiple nested loops

Example 1:#include int main(void){ int i, j, k; for(i = 0; i < 3; i ){ for(j = 0; j < !"; j ){ for( k = 0; k < !; k ){ rintf($%c$, &'& j);

rintf($ n$); return 0;

Task 1: Use nested Loops to print 3 lines of lowercase and upper casealphabets side by side. E.g: AaBb c!d"""""""..
